 angles to the axis of the main dam and about one hundred and 
 fifty feet in length: Its crest will be eight feet below the top 
 of the main dam. There will be a channel connected with it, 
 following the contour of the side hill, by means of which the 
 water flowing over the spillway will be conducted to the bed 
 of the river below. This channel will, as far as possible, be 
 excavated iu the bedrock. 
 
 Bids are requested on three distinct Plans, called in these 
 specifications and in the drawings accompanying them Plans 
 A, B and C respectively. 
 
 General 
 
 PLAN A. 
 
 ALL MASONRY DAM. 
 
 This plan provides for a masonry dam of the usual form 
 and construction, as shown on Sheets I. II and Till. 
 
19 
 
 The entire dam and spillway are to be built throughout of uu-. 
 coursed, broken range rubble masonry, built of quarry stone 
 of regular sizes and shapes, laid with full beds and joints in 
 Portland cement mortar. 
 
 The faces of the dam will be built of the same class of 
 masonry as the central portion, but the best stones and those 
 of the most regular form must be selected for the face and the 
 joints must be closer. 
 
 Both faces must be carefully pointed with Portland cement 
 mortar. 
 
 A stone coping, fifteen inches thick and three feet wide, 
 shall be laid in cement mortar on either side of the roadway 
 for the entire length of the dam and shall support the iron 
 hand railing. 
 
 Cut dimension stone will be used only for these copings 
 on the top of the dam and for the crest of the overflow weir, or 
 in such other places as may be designated by the Engineer. 
 
 PLAN B. 
 
 DAM WITH CONCRETE PIEKS AND ARCHES, 
 As Shown ou Sheets III, IV. V and VIII. 
 
 This form of dam is to be built of concrete masonry, but 
 the up-stream face will be enclosed with a thin steel plate cov- 
 ering, bolted to the concrete to prevent abrasion and the perco- 
 lation of water. 
 
 There will be in all six separate piers and two abutments, 
 joined together by circular concrete arches, both on the up- 
 stream face and on the top of the piers. 
 
 The piers will be sixteen feet in thickness aud the clear 
 spans ;5'2 feet. The extrados of the arches which support the 
 water pressure is to be cylindrical, the external radius being 
 everywhere equal to 25 feet. The thickness of the arches shall 
 be (> feet for the upper (50 feet of the dam (that is, down to el- 
 evation 4795). It shall be 7 feet for the next 20 feet in height 
 (that is. to elevation 4775 ). and 8 feet from the last given ele- 
 vation to the bedrock. 
 
20 
 
 The interior surfaces of the different sections will have 
 radii of 19, 18 and 17 feet respectively. 
 
 The arches and piers shall be built of concrete, mixed in 
 accordance with the requirements hereinafter specified for con- 
 crete and for cement. The exact proportions of ingredients 
 used will vary in the different parts. In general, the propor- 
 tions will be one part of cement, two parts of sand, and four 
 parts of broken stone for all arches and for that part of the 
 piers which is within two feet of the exterior surface; also for 
 all concrete deposited under water. In the rest of the work, 
 the proportion will be one part of cement, to three parts of 
 sand and five parts of broken stone. 
 
 The concrete shall be carefully rammed in forms or molds 
 of proper shape. For the upper faces of the arches and piers, 
 the steel plates, properly braced, shall serve as molds. 
 
 The roadway arches shall be semi-circular, the radius of 
 the intrados being 10 feet and the thickness of the arch rings 
 3 feet. They shall be 16 feet in length at the springing and 
 shall be extended to make a proper joint with the arches of the 
 up-stream face and shall be absolutely continuous with the lat- 
 ter. The spandrel spaces above the roadway arches and the 
 piers shall be filled with concrete to the level of the roadvvav. 
 A stone coping 15 inches thick and 8 feet wide shall be laid 
 in cement mortar on either side of the roadway for the entire 
 length of the dam and shall support the iron hand railing. 
 
 The steel plate facing shall be everywhere j of an inch in 
 thickness. It shall cover the entire up-stream face of the dam. 
 Steel Plates fitting closely to the concrete of the piers and arches, to which 
 it will be bolted by short bolts, as indicated in the plans. 
 
 The steel plates in front of the arches shall be rolled to 
 form a segment of a circle. The radius will be 25 feet, the 
 versed sine 8 feet, 9 inches, and the actual length of each 
 segment, measured on the arc, 43 feet, 2 inches. 
 
 The flat plates forming the facing of the piers shall be 10i 
 feet long, making a lap joint with the curved plates. All con- 
 nections between the plates shall be riveted lap splices for both 
 the horizontal and vertical joints. 
 
21 
 
 There shall be at every joint a single row of three-quarter 
 inch rivets spaced three inches apart. They shall be carefully 
 driven, the heads being closely pressed down with special 
 reference to the exclusion of water. 
 
 The edges of the plates on the upper surface shall be 
 calked, preferably by suitable machinery, so that the entire 
 sheeting shall be strictly water-tight under the greatest 
 hydraulic pressure prevailing. The edges of all plates must 
 be, in the opinion of the Engineer, sufficiently smooth to allow 
 of sufficient calking. Whenever this is not the case, they must 
 be planed off to a smooth surface. 
 
 The plates covering the arched surface shall be as large 
 as practicable so as to have the least number of joints. A 
 vertical joint shall be made on the line that the arch springs 
 from the pier, the flat plate being bent to the proper angle to 
 make a lap joint with the curved plate. 
 
 The holes for the rivets shall be laid out with templets 
 and shall be punched carefully so as to make an accurate fit, 
 but they need not be reamed. 
 
 The quality of steel for the plates and rivets is given here- 
 after under the heading "Requirements for Steel Plates and 
 Rivets.'' 
 
 The surface of the plate facing which is to come in con- 
 tact with concrete shall be thoroughly cleaned before the con- 
 crete is deposited, but shall not be painted. The outer surface 
 must be cleaned and then coated with two coats of Paraffine 
 P. & B. paint. 
 
 All paint of improper composition or badly applied, or 
 applied upon surfaces which have not been properly cleaned, 
 or where the surface has been abraded, shall be thoroughly- 
 scraped off and such surfaces repainted, as may be directed by 
 the Engineer. Painting shall be begun and continued as fast 
 as the riveting and calking will permit. 
 
 The method of procedure in building this form of dam 
 f w *'^ ( ' e l )(J11( l 1 )011 circumstances, an( l particularly upon the 
 Procedure, amount of ground water encountered. The Contractor will 
 ordinarily be allowed to adopt those methods which will con- 
 duce to the greatest economy consistent with good work. 
 Some suggestions, are, however, hereinafter given under the 
 
22 
 
 beading "Plan C." for his benefit in making a proposal, which 
 appear to indicate the most practicable methods of 'putting in 
 that portion of the dam which will be below the level of the 
 ground water. 
 
 PLAN C. 
 
 DAM WITH COXCKETE PIEI;S AND A STEEL PLATE FACING. 
 As Shown on Sheets VI, VII and VIII. 
 
 This form of dam will be built entirely of concrete mason- 
 ry and curved steel plates joined by rivets. The abutments 
 at both ends of the dam will be built of concrete. Between the 
 abutments and connecting with them, the upper face of the dam 
 will consist of steel plates supported by concrete piers, piers 
 being 11 feet (> inches thick and clear span between the piers 
 '23 feet. The piers will be connected together at the top l>y 
 concrete arches supporting part of the roadway. The lower "2") 
 feet of the steel plate face will be imbedded in a wall of con- 
 crete 15 feet thick and 'l~i feet high. The concrete in the abut 
 ments, toe-wall, arches, and two feet of thickness of piers along 
 the steel plates, shall be composed of Portland cement con- 
 crete, in the proportions of one of cement, two of sand, and 
 four of broken stone. These proportions shall alto be used 
 wherever concrete is deposited under water, and within two 
 feet of anv contact with iron work. Other portions of the 
 concrete will be mixed in the proportion of one, three and five, 
 unless otherwise directed. The bedrock shall be thoroughly 
 cleaned and all cracks shall be filled with grout immediately- 
 preceding the depositing of the concrete. 
 
 The steel plate face is designed for sheets 8 feet 10 
 inches wide (including lap) but sheets may be made of 
 any width to suit the manufacturer. Length of sheets 
 for the span plate is *2Ti feet and for the pier plate 18 feet (> 
 inches. Assuming twelve plates in the vertical height, the 
 thickuess of plates numbering from the top will be as follows: 
 
 Plates Nos. 1, 2, 3, 4, 5 and (>, $ inch: Nos. 7 and 8. 7- It) 
 inch: Nos. 9, 10, 11 and 12, A inch. 
 
 All horizontal splices will be lap joints with a single row 
 of rivets, 3-inch pitch. Vertical joints of plates Nos. 1. '1. ''> 
 and 4 will be lap joints, two rows of rivets. 34 inches pitch in 
 
23 
 
 each row. Plate No. 5 same as above, but the pitch shall be 3 
 inches in each row. All rivets in plates Nos. 1 to 5 inclusive 
 shall be steel, | of an inch in diameter. All rivets m plates 
 Nos (i to 12 inclusive will be steel, of an inch in diameter. 
 Vertical joints in plate No. (5 will be lap splice, two rows of 
 rivets, 3 1 inch pitch in each row. In plate No. 7 lap joints, 
 two rows of rivets, 2^ inch pitch in each row. All vertical 
 joints in plates Nos. 8 to 12 inclusive will be made with double 
 butt straps 10 by inches in section, with two rows of rivets 
 on each side of the joint. 31 inch pitch in each row. 
 
 All joints must be calked as far as possible by machine, so 
 as to be absolutely tight under the maximum hydraulic pres- 
 sure, and edges of plates and butt straps must be planed to a 
 bevel to facilitate calking. Edges of plates not calked need 
 not be planed. 
 
 No coating must be put on the plates until after calking 
 and riveting is done, and every precaution must be taken to 
 keep the plates free from rust and dirt. All plates to be in 
 contact with concrete must be thoroughly cleaned before the 
 concrete is deposited. Oilier surfaces must be thoroughly 
 cleaned and then coated with two coats of Paraffine P. & B. 
 paint. All paint of improper composition or badly applied, or 
 applied upon surfaces which have not been properly cleaned, 
 or where the surfaces have been abraded, shall be thoroughly 
 scraped off and such surfaces repainted, as may be directed by 
 the Engineer. Painting shall be commenced and prosecuted 
 as fast as the riveting and calking will permit. 
 
 The Engineer may decide, in lieu of paint, to put a ce- 
 ment coating to a height of 25 feet above the top of the toe- 
 wall. 
 
 The method of procedure in building the dam will de- 
 pend upon ability to control subterranean water. 
 
 It is proposed first that an excavation shall be made of the 
 whole site of the darn to as low elevation as it can be carried 
 without the use of sheet piling. After this is done, a sheet 
 pile cofferdam shall be sunk to bedrock for one of the piers in 
 the middle of the river, to be designated by the Engineer. 
 This shall be pumped out and the bedrock thoroughly exam- 
 ined, and such excavation made into it as may be directed. 
 
24 
 
 The steel plate for tlie back of this pier shall be put in 
 place and concrete deposited in the excavation so made and 
 carried to such a height as the Engineer may direct. 
 
 If, upon the investigation of this pier site, such a course 
 is deemed practicable, the steel face imbedded in the toe-wall 
 shall be put in place for its entire length and brought above 
 the surface of the water. The steel plate for the entire width 
 of the dam shall then be put in place and thereafter kept above 
 the top of the concrete. 
 
 The construction of the remaining piers can then follow. 
 
 If the above course is not deemed practicable, it is the in- 
 tention to put in a cofferdam for each pier separately, and to 
 carry them up to the elevation of the top of the toe-wall, im- 
 bedding the.steel plate in concrete in each pier, but leaving 
 the end for riveting clear by approved form of wooden protec- 
 tion. From the top of the toe-wall, the steel plate shall be 
 carried up continuously, riveting of each course being done be- 
 fore concrete is deposited against it. Subsequently, cofferdam 
 excavation shall be made between the piers for placing the 
 steel plate and portion of the toe- wall in each span. If practi- 
 cable, concrete will be laid in dry excavation, but it may be 
 decided to lay it under water. The Contractor will ordinarily 
 be allowed to adopt those methods which will conduce to the 
 greatest economy consistent with good work, the above sugges- 
 tions being made for his benefit in making Proposal. 
 
 The toe-wall being designed to exclude the water below 
 the steel plate, if crevices are discovered which would defeat 
 this, they shall be followed out above the dam, as directed, 
 and stopped by excavation and concreting, as may be directed. 
 
 Work The different parts of the work to be done under the con- 
 
 To Be Done t,. ac t may be divided as follows: 
 
 (a) Making necessary excavations in both earth and rock for 
 stripping the site of the dam and preparing the foundations. 
 
 (b) Cleaning off the bottom of the foundations, filling up 
 crevices and irregularities in the bottom, in accordance with 
 the instructions of the Engineer. 
 
 (c) Doing all pumping and other temporary work necessary 
 to keep the excavation clear of water, and taking care of the 
 
water in the river according to such methods and by such ap- 
 pliances as may be approved by the Engineer. 
 
 (d) Constructing all the masonry and steel work in the dam 
 and waste weir. 
 
 (e) Refilling those portions of the excavations not occupied 
 with masonry with earth excavated, or such other material as 
 may be selected for that purpose. 
 
 If) Doing all necessary rock and earth excavation and masonry 
 
 and concrete work necessary for the construction of a spillway 
 and overflow channel for carrying the surplus water to the bed 
 of the river. 
 
 (S) I" general, doing all work necessary for the entire con- 
 
 struction of the dam and spillway, and delivering the whole 
 structure to the Company in a completed condition, with the 
 masonry all pointed, with the dam ready to be put into service, 
 in accordance with the plans and these specifications. 
 
 It is, moreover, agreed and understood, that the prices for 
 the different classes of work, as hereinafter stated (Clause Q) 
 shall constitute full payment for the work covered by the 
 specifications and summarized in the paragraphs last preceding.

 excess shall have been ordered in writing by the Engineer, as 
 
 herein set forth. 
 
 METHOD OF PROSECUTING WORK. 
 
 Order and ^ s far ils ( '" llsistl '" t "'it' 1 the work, the order and method 
 
 Method, of prosecuting the same will be left to the discretion of the 
 
 Contractor, with whom the responsibility of such order and

 at all times have the right to prescribe and control such order 
 and methods with a view to safety, rapidity and economy in the 
 execution of the work. 
 
 PROTECTIVE WORKS. 
 
 The Contractor shall be responsible for all damage done to 
 the work bv water, whether from negligence or any other 
 cause, during the whole period of time covered by his contract. 
 He shall do all work needed to protect his work from water; 
 he shall erect all temporary dams, cofferdams, sheet piling, 
 flumes, and other devices, and shall do all necessary draining 
 and pumping. Such damage as may be caused is to be re- 
 paired by him. without cost to the Company. 
 
 The cost of furnishing the necessary appliances, of work- 
 ing them, and of pumping and draining, shall be included in 
 the prices bid for the various kinds of work. 
 
 EXCAVATION. 
 Excavation will be paid for at five (5) different prices, 
 
 Excavation for the dam. when made with sloping sides, 
 shall be measured in accordance with slopes and base given 1>\ 
 the Engineer, and will be paid for per cubic yard at the prices 
 hereinafter given (Clause Q. item a). 
 
 Earth excavation for the dam. when made in vertical 
 trench, will be paid for per cubic yard at the prices hereinafter 
 given (Clause Q, item b). 
 
 The rock excavation for the dam will be paid for per cubic 
 yard at the prices hereinafter given ( Clause Q. item c). 
 
 The earth excavation and rock excavation for the founda- 
 tion of the overflow weir and for the waste water way channel 
 will be paid for per cubic yard at the prices hereinafter given 
 (Clause Q, items d and e). 
 
Earth 
 
 27 
 
 The prices stipulated for earth excavation shall cover the 
 work of removing, handling, and transporting to spoil banks 
 and for refilling of all earth, loam, clay, sand, gravel, quick- 
 sand, mud, muck, hardpan, cemented material, stones, boulders 
 
 Excavation 
 
 ot less than one cubic yard in volume, wood, and of anv other 
 
 objects or substances found below the existing surface of the 
 ground, except rock, as specified below. 
 
 The excavation shall be made in accordance with the lines 
 and grades established by the Engineer, and the prices paid 
 for earth excavation shall include all sheeting, bracing, and 
 shoring required for supporting the sides of the excavation. 
 They shall also include all pumping, ditching, and draining, 
 and the disposal of the excavated material in sjxjil banks, which 
 shall be located at such points as may be designated by the 
 Engineer, and also for refilling such portions of the excava- 
 tion as are not occupied by the masonry. 
 
 The excavation shall be made with sloping sides or in 
 vertical trenches, as may be deemed best by the Engineer at 
 different stages of the work. The depth at which the sloping 
 excavations are to be abandoned and the vertical trenches are 
 to be begun will depend on the character of the materials 
 encountered, and cannot be fixed in advance. In any case, 
 the shores and bracing must be so disposed as to enable a 
 careful inspection of the rock bottom to be made, and so as 
 to interfere as little as possible with the laying of the 
 masonry. 
 
 The work to be done under this head consists of all the 
 earth work necessary for refilling that part of the foundation 
 pits not occupied by the stone work of the dam and waste 
 weir. The material necessary for refilling shall be selected 
 material, taken from dumps formed during the process of 
 excavation. The Engineer shall decide upon the quality and 
 Refilling. character of the earth to be used at various places for re- 
 filling, and it must be selected and placwl in accordance with 
 his orders. Care must be taken in refilling to fill all portions 
 of the foundation, so that no vacant spaces may remain. The 
 price for refilling shall be included in the price paid for 
 earth excavation. 
 
28 
 
 Kock excavation is to include the excavation of all solid 
 rock. that. is. of all material which, in the opinion . of the En- 
 Rock giiieer, cannot be removed by picking, and boulders of one 
 Excavation cu lji ( . yard or more in size. It shall be measured in excavation 
 to the lines determined by the Engineer and estimated for 
 payment in accordance with these lines only. 
 
 In preparing the foundations, the rock shall be excavated 
 on the bottom and sides of the valley to such depths and 
 widths as may be necessary to secure a proper bonding and 
 connection of the masonry to the rock, in accordance with the 
 directions of the Engineer. It may be roughly shaped in the 
 form of trenches or steps, if required by the Engineer. 
 
 All excavation of rock for the foundation of the dam on 
 Must Not the bottom and sides of the valley is to be made with black 
 Use High p l)W der. and not with high explosives. Black powder may be 
 ordered used exclusively for rock excavation where the Engi- 
 neer may so designate. 
 
 Preparing After excnvating all materials from the surface of the bed- 
 
 Founda- rock, the bedrock shall be excavated to the depth of one foot, 
 tions. O[ . more) if necessary, to obtain rock of such character as will 
 afford a good, firm foundation. 
 
 Across the dam site and parallel to its front face, trenches 
 shall be e-cavated to the depth of two feet or more, and the toe 
 of the dam shall be placed not less than two feet below the 
 natural surface of the bedrock. These trenches need not be 
 perfectly straight, but shall be excavated so as to form an ir- 
 regular surface throughout the area of the foundation, to re- 
 ceive the bottom of the foundation walls and to resist the slid- 
 ing of the whole structure upon the natural bedrock surface. 
 
 After the natural rock surface is exposed and all loose 
 rock is removed, by picking or otherwise, from the surface, the 
 whole area of the surface is to be scrubbed clean with wire 
 brooms and washed with streams from a hose, to disclose any 
 seams or fissures that may exist. If ordered by the Engineer, 
 such seams or fissures, if found, shall be followed out by exca- 
 vation until they entirely disappear, and said excavation shall 
 be filled with concrete made of one part Portland cement and 
 two parts sand and four parts broken stone: said concrete to be 
 
29 
 
 thoroughly compacted by ramming until the water flushes to 
 the surface, and allowed to set thoroughly before walking over 
 or any work is done upon it. 
 
 After the natu ral surface of the rock is prepared to receive 
 the foundation, grout shall be thoroughly worked into all seams 
 and fissures just before depositing the mortar, and not enough 
 in advance of the mortar to enable it to set independently. 
 
 In such excavations of the natural rock as above described 
 are to be laid the foundations of the dam, such foundations to 
 be well bonded and laid in Portland cement mortar, as herein 
 specified against the shoulder of the natural rock. 
 
 MASONRY. 
 
 All masonry, except where otherwise specified, shall be 
 laid in Portland cement mortar, and shall be built of the forms 
 and dimensions shown on the plans, or as directed by the En- 
 
 <nneer from time to time, and the system of bonding ordered 
 To be Laid n 
 in Portland ^ >v the Engineer shall be strictly followed. All beds and joints 
 
 Cement must be entirely filled with mortar or concrete, as the case 
 Mortar. ma ^, j^ an( j ^ e wor k j u n \\ cases must be well and thoroughly 
 
 bonded. 
 
 Care must be taken that no water shall interfere with the 
 
 proper laying of the masonry in any of its parts. All means 
 
 Contractor required to prevent water from interfering with the work, even 
 
 ast r to the extent of furnishing and permanently placing pipes for 
 
 to Prevent conducting water away from points where it might cause in- 
 
 Water in- jury to the work, must be provided by the Contractor at his 
 
 terfenng ()wn ex r )ense _ Under no circumstances will masonry, except 
 
 with work 
 
 concrete masonry, be allowed to be laid in water. 
 
 No masonry is to be built between the 15th day of De- 
 cember and the loth day of March, nor in freezing weather, 
 except by permission of the Engineer. All fresh masonry, if 
 allowed to be built in freezing weather, must, be covered and 
 Masonr protected in a manner satisfactory to the Engineer and, during 
 During hot weather, all newly built masonry shall be kept wet by 
 Hot or Cold sprinkling water on it with a sprinkling pot until it shall be-

 thought necessary by the Engineer, canvas coverings must be 
 provided. 
 
No Con- 
 structive 
 Measure- 
 ment of 
 Masonry 
 Allowed. 
 
 Dimension 
 
 Stone 
 
 Masonry. 
 
 Rubble 
 Masonry. 
 
 All masonry shall be built according to tlie plans and in- 
 structions furnished by the Engineer, and will be estimated 
 and paid for by the cubic yard of twenty-seven cubic feet, com- 
 puting only the actual volume thereof. No constructive or 
 conventional measurement will be allowed, any local rule or 
 custom to the contrary notwithstanding. The Contractor will 
 be required to furnish the materials for and to construct all 
 masonry in all places where masonry may be required by the 
 Engineer for the proper completion of the work contemplated. 
 
 Masonry will be classified as follows: Dimension stone 
 masonry, rubble masonry and concrete masonry. 
 
 f V * 
 
 Dimension stone masonry will be used only, if ordered 
 by the Engineer, for the parapet walls and copings of the 
 main dam and for the steps or crest of the overflow weir. 
 
 It shall be built of selected sandstone, limestone or 
 granite, of uniform appearance and acceptable to the Engineer. 
 The stones shall be cut to exact dimensions, and all angles and 
 arrises shall be true, well defined and sharp. All beds, builds 
 and joints are to be dressed, for the full deptli of the stone, to 
 surfaces allowing of ' inch joints at most. The face of the 
 stones shall be rock faced, or rough pointed, or hammer 
 dressed, at the option of the Engineer. The exposed surfaces 
 of the cut stones are generally to be prepared with rock face. 
 The inside surfaces are generally to be rough pointed. The 
 tops of the copings, bridge seats, etc., will generally be ham- 
 mer dressed. 
 
 Rubble masonry will be used for all parls of the all 
 masonry dam (Plan A), except where dimension stone is dis- 
 tinctly specified, or in the foundation, where concrete may be 
 used at the option of the Engineer. 
 
 Rubble masonry shall be laid without any attempt at reg- 
 ular courses. The stones shall be hard, sound, durable, of good 
 size and form, and free from dust. dirt, or other improper sub- 
 stance, and from loose seams or other defects. They must have 
 roughly rectangular forms and all irregular projections and 
 feather edges must be hammered off before the stones are set. 
 The beds must be good for materials of this class and must 
 present such even surfaces that, when lowering a stone on the 
 surface prepared to receive it, there may be no doubt that the 
 mortar will fill all spaces. Care must be taken to select the 
 
31 
 
 largest and best stones for the face work and to use the smaller 
 ones for filling the span -s and interstices. Each stone shall be 
 laid on its natural bed in a thick, swimming bed of mortar, and 
 thoroughly settled down in its place. Stones must be laid so 
 as to break joints with each other, both horizontally and verti- 
 cally, so as to insure the greatest bond and strength. 
 
 After all spaces and interstices are completely filled witli 
 mortar, fragments of stones, or spalls, shall be hammered into 
 them. Care must be taken to prevent the formation of large 
 pockets of mortar alone, and to place stones of appropriate 
 size and shape in all spaces of considerable magnitude on 
 exposed faces of walls. 
 
 The quality of the beds is to regulate, to a large extent, 
 the size of the stones used, as the difficulty of forming a good 
 bed joint increases with the size of the stones. 
 
 Various sizes must be used and regular coursing must be 
 avoided, in order to obtain vertical as well as horizontal bond- 
 ing. 
 
 The sizes of the stones used will vary also with the char- 
 acter of the quarries, but, especially in the places where the 
 Sizes. thickness of the masonry is great, a considerable proportion of 
 
 lanje stones is to be used. 
 
 O 
 
 Generally the largest stones are not to measure more than 
 twenty cubic feet, and they are to be used in the proportion of 
 about twenty-five per cent of the whole, and they must be 
 omitted partially or entirely if their beds are not satisfactory. 
 It is expected that one-quarter of the stones used will be of 
 such size that two men can handle them. The balance to be 
 composed of intermediate sizes. 
 
 If, in the opinion of the Engineer, the size and character 
 of the stones shall admit of it. the joints (except the beds), in- 
 stead of being rilled with mortar may. at his request or on his 
 approval, be filled with concrete made as hereinafter specified, 
 with the exception that the component materials shall be mixed 
 in the proportion of one part of cement to three parts of small 
 stone or gravel, of such size as the Engineer shall direct, and 
 thoroughly rammed, care being taken to use a moderate amount 
 of water only which must be brought to the surface by ramming, 
 such filling of joints with concrete to leave no vacancies and to 
 
Facing. 
 
 be thoroughly made. If concrete is so used, the spaces left be- 
 tween the stones should not be less thnu six inches, in order 
 that proper ramming can be obtained. 
 
 No extra compensation shall be paid to the Contractor for 
 the use of such concrete, the cost of which is to be included in 
 the price herein stipulated for the masonry in connection 
 with which it is used. 
 
 The faces of the all masonry dam ( Plan A ) shall be built of 
 rubble masonry laid, in general, in the same manner as the cen- 
 tral portion, so as to produce, as far as possible, a homogene- 
 ous mass. The soundest and best shaped stones shall, how- 
 ever, be selected for this work and shall be laid in such a manner 
 as to break joints and make the best possible face. All joints 
 for a depth of two inches shall, if necessary, be raked out clean 
 and shall then be carefully pointed with Portland cement mortar, 
 mixed with sharp sand in the proportion of one part of 
 cement to two parts of sand. Great care shall be taken, espe- 
 cially in the up-stream face, to produce a face impervious to 
 the passage of water. 
 
 The cost of this face stone and of the pointing shall be 
 included in the cost of dam masonry, as hereinafter stated, 
 (Clause Q, item f). 
 
 Concrete masonry will be used in the all masonry dam 
 (Plan A) to fill up irregularities in the bedrock foundation 
 and in joining the masonry to the rock at the ends of the dam 
 and also, at the option or with the approval of the Engineer, 
 in place of mortar and spalls in the heart of the dam. For 
 joining the foundation to the bedrock and in such other places 
 as he may deem proper, the Engineer may. at his discretion, 
 order the use of neat cement, in place of concrete or mortar. 
 This shall be paid for per barrel of four hundred pounds at the 
 price hereinafter stated. (Clause Q, items h and j). 
 
 Concrete masonry in Plans B and C will be used in all 
 parts of the structure, excepting the coping of the dam, the 
 Plans B&C crest and steps of the waste weir, where cut dimension stone 
 may be used, wherever ordered by the Engineer. 
 
 All concrete shall be made of Portland cement, sand and 
 broken stone, of the quality hereinafter specified. There shall 
 be two grades of concrete, paid for at different prices (Clause 
 Q, items f and g). The proportions of the mixture by volume

 be, one part of cement to two of sand and four parts of 
 broken stone in the richer grade; and one part of cement, to 
 three parts of sand and five parts of broken stone in the poorer 
 grade. The grade of cement to be used in any given part of 
 the work will be determined by the Engineer. In computing 
 the amount of cement used in a given mixture, it shall be 
 measured as packed in barrels, the cubic contents of a standard 
 barrel of Portland cement weighing four hundred pounds being 
 taken as equal to one-eighth of a cubic yard. 
 
 The volume of the sand and broken stone shall be meas- 
 ured when loose! v packed in boxes or barrows of any conven- 
 ient standard size. 
 
 A stronger mixture will be used in some parts and a 
 weaker mixture in others, the average amount of cement used 
 to be, as nearly as may be, as above stated. 
 
 In the lower and thicker portions of the piers and abut- 
 ments, the Contractor will also be j>ermitted to embed in the 
 concrete a considerable portion of larger stones, not to exceed 
 about ten cubic feet in volume. These stones shall be of proper 
 shapes, they shall be thoroughly wet before being used and 
 shall be so laid as to be entirely enclosed by concrete on all 
 their surfaces. There shall be at least twelve inches of con- 
 crete between any two adjacent stones. The proportion of 
 stones to be embedded and their size and shape shall be at all 
 times subject to the approval of the Engineer. 
 
 The method of making all concrete shall be the following: 
 The sand and cement shall first be properly mixed together 
 dry, then formed into mortar by adding a proper dose of clean 
 water and again thoroughly mixed, whereupon the ballast, 
 properly moistened, shall be quickly added and mixed with 
 the mortar, either in an approved machine, or by rapidly turn- 
 ing over the mass with the proper tools upon a suitable plat- 
 form twice or more times, as the Engineer may direct. The 
 resulting concrete shall be free from surplus water, but thor- 
 oughly moistened throughout, and the voids between stones 
 shall be completely filled with mortar in excess. As soon as 
 the mixing is completed, the concrete must be deposited rapidly 
 Admixture in the place where it is required and thoroughly rammed and 
 with Mortar p OU1K ] e( ] 7 j n a manner satisfactory to the Engineer, until 
 th water flushes to the surface and all the spaces are entirely

 filled with morta''. Should voids afterwards be discovered, the 
 defective work is to be removed and the spaces refilled with 
 suitable material at the Contractor's expense Any concrete 
 mixed aud left standing so as to take an initial set shall not be 
 used in the work. In no case shall mortar or concrete that has 
 been left standing over night be used. Care must be taken 
 against too severe or long continued pounding, thereby forcing 
 the broken stone to the bottom of the layer, or disturbing the 
 incipient set of concrete. In all cases, the concrete must be al- 
 lowed to set for a sufficient time after being deposited in place, 
 before walking over or working upon its surface is permitted. 
 The time thus required shall be determined by the Engineer. 
 
 In case it is necessary to lay concrete in water, the mate- 
 rial shall not fall from any height, but shall be deposited in a 
 compact mass in the allotted place by the use of such appli- 
 ances as will be approved by the Engineer. 
 
 In building the concrete piers and arches ( Plans B and C) 
 great care shall be taken to obtain a thoroughly sound and uni- 
 form grade of concrete in each part of the work. The molds 
 shall be securely and strongly built of plank at least two inches 
 in thickness and they must be thoroughly secured in every di- 
 rection by bracing, so as to insure the correct shape aud posi- 
 tion of the concrete work. The plank used shall be tongued 
 and grooved, with a smooth surface on the inner side of the 
 mold, and tightly fitted together, so as to leave very small 
 joints aud as finished a surface as possible. 
 
 If necessary, to prevent adhesion, the inner surfaces of 
 the molds shall be painted with a thin coat of crude black oil. 
 
 The outer surfaces of the concrete work must be smooth 
 and perfect, showing as few large stones and marks of the 
 mold as possible. 
 
 Plastering of the finished wall will not be required unless 
 the above result should not be obtained during the filling of 
 the molds. To insure this, a portion of the mortar used in 
 making each batch of concrete shall be retained and used, 
 without the addition of broken stone, for those portions of the 
 work nearest the face. In doing this, the mortar shall be piled 
 up for each layer in a triangular heap close to the molds, thus 
 making a bond with the central portion of the work. After the 
 molds are filled, they shall not be removed for at least three 
 
35 
 
 days, or longer if necessary, and the concrete shall be sprinkled 
 and kept wet, as long as may be deemed necessary by the En- 
 gineer, to prevent cracking. 
 
 The broken stone for concrete shall consist of fragments 
 of durable stone, broken so as to measure no more than two 
 inches in any direction. All this material shall be free from 
 Broken dust, dirt, clay, or other improper substance and, when re- 
 Stone, quired by the Engineer, it shall be washed before being mixed 
 with cement mortar. Any material under J of an inch in 
 diameter, unless required by the Engineer to be screened out, 
 shall be counted as so much additional sand and the volume of 
 sand reduced proportionately. 
 
 Sand shall be clean, coarse, and silicious; it must be 
 screened and washed, if required by the Engineer, and must 
 be subject to his approval as to fineness and other qualities. 
 
 CEMENT. 
 
 In. the construction of the dam and in all other w y ork con- 
 nected with it, Portland cement is to be used, which must be 
 of a superior quality. It shall be well packed in strong bar- 
 rels of standard size, so as to be reasonably secure from air. 
 
 Vigorous and continuous tests will be made of all cements 
 to be used. Samples may be taken from each and every barrel 
 and a failure of one-tenth of the samples tested ruav be suf- 
 ficient cause for the rejection of all barrels in the same lot from 
 which the samples have been taken. 
 
 Tensile ^ e standard test use ^ will be the testing for tensile 
 
 Tests. strength of standard briquettes of i/m/ cement, one inch square 
 
 at their least section. 
 
 All cement to be accepted must conform to both of the 
 following tests: 
 
 When left one hour in the air and the balance of 24 hours 
 in water of a temperature of about 60 degrees, the briquette 
 shall stand a tensile stress of at least 100 Ibs. per sq. in. before 
 breaking. When left 24 hours in the air and six days in water 
 of a temperature of about (iO degrees, the briquette shall stand 
 a tensile stress of at least 300 Ibs per sq. in. 
 
86 
 
 The degree of fineness shall be such that at least 85 per 
 cent, shall pass through a standard No. 100 sieve, (10,000 
 meshes to the square inch). A cement that cracks or checks 
 when made into thin cakes, or that begins to set in less than 
 twenty minutes, shall not be accepted. 
 
 It must also test and act to the satisfaction of the Engi- 
 neer when mixed with sand, and will be subject to constant in- 
 spection. If other than the tensile, tests ordinarily made seem 
 necessary to the Engineer, he shall have the privilege of con- 
 ducting the same and, if the cement fails to pass any of them 
 to his satisfaction, it shall be rejected. No charge shall be 
 made for samples of cement taken for such tests. The Con- 
 tractor shall at all times keep in store, at some convenient 
 Cement point in tha vicinity of the work, a sufficient quantity of ce- 
 ment to allow ample time for the tests to be made, without de- 
 lay in the work of construction. It shall also be stored in a 
 tight building and each cask must be raised above the ground 
 bv blocking, or otherwise. As soon as notified of the arrival 
 of the cement, the Engineer will cause to be made such tests 
 as, in his judgment, may be uecessarv. If any cement is found 
 of improper quality, it shall be branded, and must be imme- 
 diately removed from the work. 
 
 PLANS B AND C. 
 
 STEEL. 
 
 The treatment and manufacture of the steel plates and 
 Steel Plat s r * ve * s use d in the facing of this form of dam shall conform in 
 andRivets. all respects to the following requirements and to the detailed 
 drawings to be furnished for this work. 
 
 REQUIREMENTS FOR STEEL PLATES AND RIVETS. 
 
 The steel shall be of the class termed "soft medium'' and 
 shall be made by the open hearth process, either the basic pro- 
 cess or the acid process, as the Engineer may determine. If 
 made oy the basic process, the percentage of phosphorus shall 
 not exceed .04 and of sulphur not be greater than .04: if made 
 by the acid process, it shall not contain more than .07 per cent, 
 of phosphorus and not more than .04 of sulphur. The per- 
 centage of manganese shall not be greater than .60 per cent. 
 Each sheet shall be uniformly homogeneous in quality, and 
 
Chemical 
 Analyses. 
 
 Physical 
 Tests. 
 
 should n reasonable doubt exist as to the quality or uniformity 
 of the steel furnished, the Engineer may order additional tests 
 before acceptance. 
 
 A sufficient number of chemical analyses of each heat or 
 melt, to determine the quality of the steel, shall be made by 
 the manufacturer without expense to the Company, and proper- 
 ly certified copies of the final analyses of the finished material, 
 giving percentages of carbon, phosphorus, manganese and 
 sulphur, sliall be furnished to the Engineer of the Power Com- 
 pany, or his representative, as the work progresses. 
 
 Physical tests to determine the tensile strength, elastic 
 limit, softness and ductility of the material of each heat or 
 melt shall also be made at the expense of the Contractor by an 
 experienced Inspector, whose services shall be satisfactory to 
 the Chief Engineer of The Pioneer Electric Power Company, 
 and who shall keep a complete record of all analyses and tests 
 identifying each by its respective melt number. Such record 
 shall be open to inspection of the Engineer at any and all 
 times. 
 
 For the purpose of identification, the heats or melts shall 
 be numbered consecutively and the corresponding number 
 stamped upon each plate or sheet produced therefrom. A lack 
 of sufficient identification may be cause for rejection of an en- 
 tire heat or melt. 
 
 Test pieces shall be furnished from at least twenty per- 
 cent, of the finished material of each melt, but at least two test 
 pieces shall be made from every melt. The plates or sheets 
 Furnished, from which test pieces are taken shall be selected at random 
 by the Inspector, and each piece shall be numbered with the 
 corresponding melt number. 
 
 Tensile test pieces shall be at least sixteen inches long and 
 shall have, for a length of eight inches, a uniform planed edge 
 . sectional area of at least one-half square inch, the width in no 
 case to be less than the thickness of the piece.

 Test pieces as above shall give results as follows: Ulti- 
 mate strength, 55,000 pounds to 65,000 pounds. Elastic limit, 
 not less than one-half ultimate strength. Elongation, not less 
 than 24 per cent, in eight inches. Reduction of area at frac- 
 ture, at least 48 per cent. 
 
 All fractures shall be fine, silky and free from crystalline 
 appearance, or from indications of injurious treatment or in- 
 sufficient working. 
 
 Bending test pieces shall bend double under the hammer, 
 cold, without signs of cracking. 
 
 In punching test pieces, a row of eight holes. of an inch 
 in diameter and 1^ inches between centers shall be punched 
 without any cracks. 
 
 In drifting test pieces, not less than two holes, ^ of an 
 inch in diameter, spaced two inches between centers, shall be 
 punched and then enlarged by blows from a sledge hammer 
 upon a di if ting pin until said holes are 1^ inches in diameter, 
 without showing signs of failure or cracking on the inside of 
 the hole or edge of the plate. Punching and drifting tests to 
 be made cold. 
 
 The plates must also admit of cold hammering or scarfing 
 to a fine edge at the laps without cracking, and the test pieces 
 must furthermore withstand such quenching, forging and other 
 rests as may satisfy the Inspector as to the temper, soundness 
 and fitness for use of the material. 
 
 Any failure of test pieces, taken at random as aforesaid, 
 
 Failure of to conform to the above requirements may. at the discretion of 
 
 Test Pieces the Engineer or Inspector, cause the rejection of the entire 
 
 product of the heat or melt from which such pieces are taken. 
 
 All finished material shall be free from laminations, cracks, 
 blisters, scale or cinder sjx)ts. and have clean edges and good 
 surface free from bends. The plates shall be fully up to the 
 required thickness at all points. Any plate whose thickness 
 of Plates, at any point may be found less than the required thickness by- 
 more than 1-100 of an inch shall be rejected without appeal. 
 Plates varying more than five per cent, from the weights per 
 
39 
 
 square foot given in the table below, will be rejected and no 
 allowance will be made for weights more than five per cent, in 
 excess of the standard weights required.

 The plates shall be rolled as flat as good mill practice will 
 
 permit and each plate shall be cut to the dimensions required. 
 
 A variation of more than one-fourth of an inch from the dimeii- 
 Variationin sions required on either length or width of plate will not be 
 Dimensions permitted and in no case shall they be scant of the required 
 
 dimensions. All material shall be finished in a first-class, 
 
 workmanlike manner. 
 
 The Engineer of the Power Company, or his representa- 
 tive, shall have the right at all times to inspect the process of 
 manufacture and testing of any and all plates, and may have, 
 Additional in his discretion, an additional number of test pieces, not more 
 Test Pieces ^| lau one-fourth of the whole, prepared as above from such 
 melts as he may designate, for testing under his own super- 
 vision, at the expense of the Power Company. 
 
 It is understood and agreed that any plate that shows any 
 defect during the process of punching, bending, or riveting 
 shall be rejected, notwithstanding that Ihe same may previous- 
 ly have 'been satisfactorily tested. 
 
 Rivets shall be made of a good grade of soft steel and 
 shall have a tensile strength between the limits of 56,000 
 pounds and 64.000 pounds per square inch, with an elastic 
 limit not less than 36,000 pounds and shearing strength not 
 less than seventy-two per cent, of the ultimate strength.

 Physical tests shall be made by the Inspector to determine the 
 elongation and area at the point of fracture. In an ordinary 
 Rivets. t es t piece, as described above, the elongation shall be not less 
 than twenty-seven per cent., and the reduction of area at point 
 of fracture not less than fifty-four per cent. The material shall 
 also be of such quality as will stand bending double and flat, 
 before and after heating to a light yellow heat and quenching 
 in cold water, without sign of fracture on the convex surface 
 of the bend. All rivet material not conforming to the above 
 requirements shall be rejected. 
 
 All plates and rivets must be free from rust and kept un- 
 der cover from the time of manufacture of the plates. At the 
 factory, the plates must be loaded under cover upon suitably 
 
 covered cars. They must be delivered under cover at their 
 be kept free 
 
 from rust, destination and must be kept under roof and cover until ready 
 for shipment, and in no way exposed to the weather or mois- 
 ture. In case of accidental rusting, the rust must be removed 
 from the plates before placing them in the structure for which 
 they are intended. 
 
 STEEL OE IKON FENCE. 
 
 On both sides of the roadway on top of the dam, for its 
 ompany ell |j re length, an ornamental wrought iron or steel fence shall

 Plans for this fence shall be furnished by the Engineer. 
 
 The fence will hare well braced posts, securely fastened 
 to the coping, placed about eight feet between centres, with a 
 close lattice work placed between the posts. The weight of 
 the fence, including posts, will be about fifty pounds per lineal 
 foot. It shall be painted two coats of an approved white lead 
 paint. 
 
 The fence will be paid for per lineal foot at the price 
 hereinafter stated, Clause Q, item (1).

 work, the Contractor shall lie fairly remunerated; and, in case 
 they shall diminish the cost of the work, a proper deduction 
 from the contract price shall be made; the amount to be paid 
 or deducted to be decided by the Engineer. 
 
 L. The Contractor hereby agrees that he will do such extra 
 
 work as may be required by the Engineer for the proper con- 
 struction and completion of the whole work herein contem- 
 plated : that he will make no claims for extra work unless it 
 shall have been done in obedience to a written order from the 
 said Engineer, or his duly authorized agent; that all claims for 
 
 Extra work. 
 
 extra work done in any month shall be hied in writing with the 
 Engineer before the second day of the following month; and 
 that, failing to file such claims within the time required, all 
 right for pay for such extra work shall be forfeited. The price

 to be paid for all extra work done shall be its actual reasonable 
 cost to the Contractor, as determined by the Engineer, plus 
 fifteen per cent, of said cost. 
 
 M. The Contractor is to use such appliances for the perform- 
 
 ance of all the operations connected with the work embraced 
 under this contract as will secure a satisfactory quality of 
 work and a rate of progress which, in the opinion of the Engi- 
 neer, will secure the completion of the work within the time 
 herein specified. If. at any time before the commencement or 
 Appliances, during the progress of the work, such appliances appear to the 
 Engineer to be inefficient or inappropriate for securing the 
 quality of work required or the said rate of progress, he may 
 order the Contractor to increase their efficiency or to improve 
 their character, and the Contractor must conform to such or- 
 der; but the failure of the Engineer to demand such increase 
 of efficiency or improvement shall not relieve the Contractor 
 from his obligation to secure the quality of work and the rate 
 of progress established in these specifications. 
 
 N. The Contractor further agrees that, if the work to be done 
 
 under this contract shall be abandoned by him, or if at any 
 time the Engineer shall be of the opinion, and shall so certify 
 in writing to the board of directors of the Company, that the 
 said work is unnecessarily or unreasonably delayed, or that 
 violations of * ne sa *^ Contractor is wilfully violating any of the conditions 
 agreement or agreements of this contract, or is not executing said contract 
 in good faith, or fails to show such progress in the execution 
 of the work as will give reasonable grounds for anticipating 
 its completion within the required time, the Company shall 
 have power to notify the Contractor to discontinue all work, or 
 any part thereof, under this contract; and thereupon the said 
 Contractor shall cease to continue said work, or such part 
 thereof as the Engineer may designate; and the said Company 
 shall thereupon have the right at its discretion to contract with 
 other parties for the delivery or completion of all or any part 
 of the work left uncompleted by the Contractor, or for the cor- 
 rection of the whole or any part of said work. And, in case 
 the expense so incurred by the Company is less than the sum 
 which would have been payable under this contract if the same 
 had been completed by the Contractor, then the Contractor 
 shall be entitled to receive the difference; and in case such ex 
 pense shall exceed the last said sum, then the Contractor shall,
