) 071 Suggestive Outline in Woodwork and Drawing 703 For Grades and High School ALSO A Preliminary Statement Regarding Work in Metal and Cement 5 1 5 6 5 ___, Prepared by J. M DORRANS State Supervisor of Manual Training Issued by C. P. GARY State Superintendent Madison, Wisconsin 1917 MANUAL TRAINING AND INDUSTRIAL EDUCATION SUGGESTIVE OUTLINE FOR WOODWORK AND DRAWING In order that manual training and industrial work may be most fruitful of results, it is absolutely necessary that the de- velopmental and broadening side of the work receive as much attention as the actual performance by the hands. The knowl- edge of how to distinguish a particular kind of wood or metal, its characteristics and properties is quite as valuable and de- velopmental to a student as the accomplishment of making some object with his hands. Hand work without thinking and planning is deadening in its effects. A visit to a factory, build- ing yard, foundry, or lumber mill under the careful guidance of the instructor will give the student an insight into the indus- trial world that will be of great profit to him. A report of such visits may be written up for the English work. Community Work In the past, manual training has had a tendency to encourage pupils to become selfish and to think of their own interests rather than the common interests of the school and the com- munity. Pupils should be trained and encouraged to become as interested in doing work for the school or public good as though -it were for themselves. This is a step in the direction of true citizenship. Free-hand drawing on coordinate paper might well receive more attention in the grades and high school work. It should be correlated with the shop work whenever practicable. Time should be taken in the seventh and eighth grades to sketch the projects that are under construction by the class. 2066706 New Ideas and Inventions Discuss any new idea or invention with the class that is re- lated to the shop or industries. Make such points as where the invention will be most helpful, how will it affect the people as a whole, what effect, if any, it will have in our daily life. Bulletin Board Have a bulletin board for cuttings on interesting subjects, and encourage the boys in the class to bring these cuttings. For example, many interesting cuttings may be taken from The Popular Mechanics Magazine or from The World's Work. Notebooks It is a good plan for the teacher to keep a good loose leaf notebook with short notes on his subjects, and to add to them when opportunity offers. If the, notebook is of such a size that it can be carried conveniently in the pocket, more helpful ma- terial will find its way into it than if it were one of a large and bulky nature. The pupils should also keep notebooks. Demonstrations The teacher is usually able to demonstrate enough in fifteen or twenty minutes to keep the class busy for the remainder of the period. A schedule of demonstrations and lectures should be worked out by the teacher for the entire year. Charts and Drawings Charts may be made by the high school boys for grade work. They save the time of the teacher in placing the drawings on the blackboard. Accuracy The question of how accurate the work should be done must rest with the teacher. He must study the individual pupil and be satisfied that the work of each boy is the best he is able to accomplish at that particular stage of the work. Rural and city districts may demand different problems. Card Systems Schools that have printing presses may print coupon books for the Manual Arts Department. When lumber is obtained from the rack by members of the class, a coupon for the amount is torn from the book and filed with the teacher. A card show- ing the itemized and total cost of the project should be worked out by each pupil before starting the construction. Problems Arranged by Groups This outline of woodwork has been planned with the object of setting out the problems in cycles or groups. That is, after the first or second problem has been made, the members of the class may have a choice of one of a number of possible problems. This method or plan allows the teacher to suggest to a boy a problem that will be adapted to his ability and at the same time command his interest. This does not necessarily mean the mak- ing of some large problem, but rather one that calls for the maximum amount of judgment of the hoy. The arrangement of groups also permits the presentation of the important opera- tions by means of a demonstration, thereby relieving the teacher of the necessity for simply repeating instructions throughout the period. Models When possible, it is a good plan to have models made to rep- resent the various groups of projects. (High school boys may help in this work.) A boy may not be interested by being told the name of some project he may make, nor yet by seeing the drawing, but may be very much interested when he sees a model of the completed problem. Demonstration and Topics An arrangement of a platform and seats with a demonstra- tion bench where the class meets at the beginning of each period for the demonstration is urged. This platform may be in the manual training room, if there is sufficient space, or in a room adjoining. The demonstration should not be long, preferably not over fifteen minutes. A short review of the work of the 6 last period should be taken up and then the demonstration pro- ceeded with. The teacher should endeavor to have some interesting topic on the work to present to the class in the event of no demon- stration. A short talk on the woods that are being used in the work shop, where grown, characteristics, local price per foot, and common uses could be given. CEMENT WORK The development of cement work in schools offering manual training is recommended. This may be given in the eighth grade or the first year of high school. It will be found especially valuable and makes a good correlation with carpentry and agriculture in schools offering agricultural courses in the grades or high school. Many projects in cement can be worked out for the school or community. Such work as foundations for playground apparatus, sidewalks, and floors, offer good elementary community problems. Feed troughs, silo foundations, flower boxes, pedestals, fence posts, lawn seats, and milkhouses can also be worked out. Old forms can be worked over again and in this way the expense for stock kept down to the minimum. Carpentry Cement work suggests a good correlation with that type of carpentry work which is suitable for schools. The building of a barn, garage, or plain cut house would form an excellent project in correlation of the carpentry and cement work. A detailed outline of cement and carpentry work will be worked out as soon as possible. METAL WORK The development of metal work in our schools is urged. It is gen- erally true that we devote too much time to woodwork at the expense of a more valuable and broader development that would accrue from working with metal in addition to working with wood. This additional experience would also be of value in assisting the pupil to choose a vocation. The following outline for the development of metal work will come within the reach of the smaller high schools, and in the larger cities, part of it may be introduced in the grades. Electrical wiring could be introduced in the seventh or eighth grade. The course should be outlined to give from about three to five months IJ to the subject. It could be correlated with elementary science in the junior high school. Forge work, sheet metal work, light plumbing, could find a place in the eighth and ninth grades. In many schools the logical place for this phase of the work would be in the ninth grade because of the larger number of nonresident pupils that come to the high school in the ninth grade. Gas engine and automobile op- eration and mechanism could be placed in the sophomore year. In schools offering a four-year course in manual arts, machine shop, pat- ternmaking, and foundry work could be given in the junior year, and the senior year could be one of special study in some one or two courses. A detailed outline of metal work will be worked out by this depart- ment and furnished to schools as soon as possible. Suggested Minimum Manual Training Equipment for High School, 16 Boys.

Lecture on Lumber Tree development: Growth, structure, cells, annual rings, density of spring and summer rings, age of tree from rings. The giant redwoods of California. Classification of tree: Exogens, yearly growth by rings, these trees furnish our lumber. Endogens: Growth is maintained from the inside of tree, no an- nual rings; palm, bamboo, cane, are examples. Sawing Lumber: Method of sawing; plain and quarter-sawing; quarter-sawn boards cut parallel to medularry rays. Find rays on cross and surface section of oak. Stacking Lumber: Grades, kept separate. Board graded from the best face. Seasoning: Air drying, care in piling to prevent decay, and discolor- ation; seasoning reduces weight, saves freight. Kiln Drying: Quickest and best method of drying. Various meth- ods. Drying increases strength of wood. Hardwood requires longer time to dry than soft wood. Warping: Caused by one side of board drying out faster than the other side. Heartwood side of board shrinks slower and less than the sap side. Quarter-sawed boards remain true owing to the cells on both sides of the board being equal in density and consequently drying out at the same rate. 12 Section of a tree: Pith, heartwood, sapwood, cambium layer, bark. medullary rays, cause of knots. Prices of lumber: Plain, quarter-sawed. How sold. A primer of forestry I and II may be had on application to the forestry department of agriculture, Forest Service, Washington, D. C. Directors and supervisors should have their names listed with the United States Department of Agriculture, Washington, D. C., to re- ceive the monthly list of bulletins published by that department. Group 6. Accurate edge jointing group: Use of dowels, groove, screws, (cleats). Suggested problems: Drawing board, baking board, bread board, (hardwood, light and dark), tabouret, checker board; prob- lems suggested by the class that come within this group. Design: Design to be in keeping with the service of the project. Baking and drawing boards being so designed and constructed that they will not warp. New Operations: Laying out for dowels, doweling. Tounging and grooving with plane. 'Clamping. Demonstration: Have chart showing various methods of gluing and joining edges together. Demonstrate making of dowel joint. Demonstrate use of straight edge and winding sticks. Points to emphasize: Accuracy in laying out centers for dowels. Length of dowels. Method of clamping. Development topics: Screws; kind, comparison of the merits of steel blued and brass screws, what the number on the package of screws means; price, etc. Twist driving nails. Lag screws and bolts compared. Holding power of nails and" screws compared. A sample board with samples of the various kinds of screws, should be made up and used for lecture and reference purposes.

Illustrate laying out by superposition. Points to emphasize: Need for accuracy in laying out joint. Emphasize the use of knife in laying out lines. Stock should be square and parallel in width. Method of gaging depth of joint. Development topics: Gouges: Kinds, inside, outside, and short bend. Regular, middle, and flat sweep. Woods: A study of the common woods, their characteristics and principal uses should begin not later than at this point in the course. The plan should be to have pupils compare the character- istics and properties of a new wood with one which they are already familiar with. Logs about 24" long and so cut that there will be a cross section, a radical section, and a tangent section shown will be found most helpful for illustration work. Group 8. Irregular surface group. New tools: Outside, and short bend gouge, router, templates. Suggested problems: Canoe paddle Single tree Picture frame (ellipse) Clothes stick Fish plank Model boat Hand mirror frame X^rumb set Operations: Gouging or spokeshaving irregular surfaces. Material: Suited to the purpose of the problem. In the case of the fish plank white oak will be found suitable. Design element: This should be subordinated to its particular purpose or service. Demonstration: The use of the gouges or other necessary tools should be demonstrated in the completion or part completion of a problem. Points to emphasize: Method of holding outside and bent gouges. Symmetrical outline. Smooth surface from tools be- fore sanding. Development topics: Kind of metal edge tools are made from. Kinds of steel; difference between steel and iron. Effect of tempering. 14 The story of lumbering: Stereoptieon slides of this subject are loaned by the United States Department of Agriculture, Forest Service, on condition that transportation expenses and break- ages are paid by the borrower. Boys would be interested in reading "The Blazed Trail" by White. Slides and films on industrial subjects may be borrowed by schools without expense from the Extension Division of the Uni- versity of Wisconsin. Borrowers pay transportation charges and as- sume risk for breakage. Group 9. Mortise and tenon group. Suggested problems: Footstool, umbrella rack, picture frame, window screen, porch swing, window fern box (with legs) zinc lined. Double bottom may be provided with sponges and cor- ner filler for water. Operations: Boring, method, chiseling, method, sawing or chisel- ing tenon. Material: Suited to the purpose of the projects. Design element: This should be suited to the problem and the ability of the individual. Demonstration: Lay out and demonstrate making of mortise and tenon joint. Compare mortise and tenon with doweling. Points to emphasize: Method of laying out, size of shoulder, length of tenon, thickness of tenon, boring and chiseling, cut mortise first. Pupils make practice joint before beginning problem. Note: It is well to see that the boy selects a problem that is within his capabilities. Development topics: A comparison of the holding power of dow- els and mortise and tenon joints may be taken up with the class. Making doors in a factory. Machine made and hand made joints. ADVANCED WOODWORK FOR INDUSTRIAL AND HIGH SCHOOLS In beginning the woodwork in the high school, it may be a good plan to review the work given in the latter part of the eighth grade. This review should be made vital and a contrast drawn between the work of the grades and the larger demands of the high school work. The course may be .started with the mortise and tenon joint. A practice joint with two rails and with the tenons meeting in the post necessitating the mitering of the tenons should be made. In order to encourage the pupil to do his best, it is a good plan to suggest that if one good mortise and tenon joint of the problem is made by hand, the remaining mortises and tenons will be allowed to be finished on the machines. This plan is usually effective in producing a first-class joint that is worth more than any number of poorly made ones. 15 Conserving the time of the class: By the use of machines much of the heavy monotonous repeat work is eliminated. The pupil is capable of accomplishing more in less time, thereby gaining a wider range of experience and knowledge proportionally. To be trained in industrial methods on machines and to have had that training under a capable teacher is a valuable experience. Use of machines: Before a pupil is allowed to use any machines, it is essential that the machine be properly guarded. No pupil should be permitted to use a machine before having a thorough understanding of the use of the attachments and the proper position while working at a machine. The danger from poor technic should be emphasized. A mat made from rubber or asphalt roofing ma- terial should be placed in front of all machines for pupils to stand on when operating machines. DONT'S FOR PUPILS AT MACHINES Don't take a chance with a machine. Don't try to hurry because someone is waiting. Don't talk to anyone while working on a machine. Don't do anything your teacher has asked you not to do. Don't stand on cuttings while working on a machine. Don't start up a machine and begin to figure. Don't forget to use a "push stick" when sawing narrow pieces on a ripsaw. Don't lower or raise a saw table to an angle before fastening the guides on the saw table. Don't raise the guide post of a band saw after starting the ma- chine. Don't forget to shut off a machine when oiling it. Don't fail to tell your teacher if a machine is broken or out of order. Don't try to balance yourself on one foot when working on a machine. Don't run a short piece of stock across a jointer without a push block. BEGINNING ADVANCED WORK SELECTION OF MATERIAL Before beginning the work of making a project, a lecture on the selection of material should be given. Emphasis should be placed on the saving of stock, the method of planing stock, that is afterwards cut into shorter pieces, should also be brought out. 16 When practical, all material for the problem should be gotten out at one time. First Problem For the first problem made on the machine, it is suggested that it should be of the skeleton type without panel or door construction. A problem of this nature will give the pupils simple duplicate prac- tice work and will familiarize them with the machines before at- tempting anything more advanced or complicated. Furniture Parts The different parts of a piece of furniture such as rails, styles, panels, etc., should be made known to the class and they should al- ways be called by their proper names. Industrial Methods The factory method in getting out stock on the machines should be followed as far as machines and equipment will permit. Suggested skeleton problems: Stool, telephone table, manual training bench, piano bench, fern or flower stand for window (with legs), draft screen, plain table, umbrella stand; sugges- tions from pupils. Tools: Any tools required for the work. Operations: Gluing up leg material if over 2" square. Cutting mortises by hand or machine. Cutting tenons by hand or on machines. Assembling. Material: Any material that is in keeping with the use and de- sign of the project. Design: Emphasis should be placed on good spacing and good construction. Demonstration: Demonstrate the proper method of matching and gluing up legs and the proper method of applying hand screws. Points to emphasize: Do not glue up stock in a draft. Proper condition of glue. Importance of working rapidly. Time for glue to dry. That the joints of the legs when assembled all face in the same directions. LECTURE ON GLUE Kinds: Hide; vegetable; cold. Merits of each and where used. Preparation: Soak flake glue in plenty of cold water in a cool place for three or four hours, pour off the surplus water that the glue has not soaked up and place glue in heater. Temperature of glue about 145 F. Kinds of heater: Electric: (usually copper, brass, or aluminum kettle.) Steam, gas or oil. Glue that has been reheated loses its strength with each reheat- ing. Glue that smells sour should not be used. Thin glue with clean hot water. Heat wood if cold. 17 Second or third problem. In this advanced group, either panel drawer or door construction or a combination of these should be considered. Three-ply panel stock should be used when practicable. LECTURE OX TABLE OB DBESSEB LJEG CONSTRUCTION Shape or leg: Straight, curved, tapered, turned. Construction: Solid, built up, veneered. Points to consider: Solid leg: Quicker, no gluing; no joints to show; danger of checking from drying. If over 2" square, leg should be built up. Checking: Heavy stock is not usually properly dried; as a re- sult, it checks readily. The quarter-sawed effect can be obtained on two sides only. Built up leg:- Built up or veneered leg may cost more. Veneered or built up leg may have quarter-sawed face on all four sides. Built up leg is not likely to check. Sketches: Illustrate the various joints and methods used in building up legs. LECTUBES ON INLAY WOBK Historical: A few minutes' talk on the inlay work as practiced in some of the eastern countries in ancient and modern times. Ancient inlay materials gold, silver, mother-of-pearl, ivory, bronze, wood, etc. Inlay: Inlay is the setting in of some wood or other material, in contrast to the solid material. Sometimes filler is used in place of wood for a narrow surface to give inlay effect. Marquetry: Marquetry is the practice of cutting thin veneer into pieces in contrast to each other, but unlike inlay are glued on the surface rather than set into the solid wood. Parquetry: Parquetry is a kind of mosaic of wood used in floor- ing. It is usually cut in geometrical forms and laid edge to edge. Sometimes it is solid and sometimes it is in veneer about W in thickness. Depth of Inlay: Generally inlay material is not any heavier than 1/16" in thickness. Cutting Marquetry Patterns: Marquetry patterns are usually cut with a very fine jig or fret saw from a pattern. Designs: Inlay: Inlay should be kept in harmony with the de- sign of the object. Very often simple narrow contrast line design will relieve the monotony of a surface. Inlay of vari- ous designs may be purchased glued up ready to inlay. 18 Cutting groove for inlay: When possible, this should be done on the saw, using the crosscut saw for both crosscut and ripping of the groove. The corners may require to be finished by hand. It is a good plan to have a special cutter about %" wide and a groove filed in the center leaving a cutter on each side for use in a marking gage when cutting groove by hand. Staining: If staining over inlay, it will be necessary to coat the inlay with a thin coat of white shellac to be rubbed off after staining and filling. DEMONSTRATION ON ASSEMBLING A PROBLEM Gluing up one side at a time. Importance of each part being square. Sanding of certain parts before gluing. Avoid get- ting too much glue in the joint. Method of testing diagonally across the corners for squareness when assembling frames of tables or stools. Method of removing surplus glue from joints when hard. Use of dowels or nails where not seen, to give ad- ditional strength to joints. Importance of having everything ready for rapid work when assembling. LECTURE ON DESIGN Two or three- lectures on design should be given, embracing the following: Obtaining definite dimensions. Good proportion. Horizontal and vertical spacing. Method of designing a dresser or buffet. Use of ornament. Carving, inlay. Finish. Gluing up Table or Buffet Tops Lecture and Demonstration Proper selection of materials: This should be carefully selected with regard to grain and size of flakes, if quartered. A top gen- erally should never be less than %" in thickness and if glued up solid, it is better not to exceed l 1 ^" in thickness. Matching: This should be done with some regard to keeping the large flake or figure in the center of the top and the smaller flake running out toward the edges. Width of pieces: It is often desirable for the appearance and to help in the reduction of warping, where the top is made of plain stock, not to have the pieces too wide. 19 Warping: Warping of a table top is likely to happen if the under side is not so treated that the action of the pores of the wood are stopped, or if not properly held in place. Joints: A dowel joint is perhaps the most suitable for school work. The dowels should be about l 1 /^" to 2" long in each side of the joint and should not be further than about 1%" from the finished end. Joints should be about 1/64" in 40" hollow in length be- fore gluing. It is sometimes advisable to give the end wood a coat of shellac to protect joints from opening up. Sketches: Illustrate the various joints used in commercial practice in gluing up tops. Sketch methods of building up heavy tops. Dowels: Method of laying off for dowels. Have samples of various kinds of dowels. Method of gluing dowels. Number required on each joint. Clamping: Method of clamping up top when gluing. The use of cross cleats clamped on the ends with handscrews to prevent bending while clamping. Special tressel clamps. Attachments for jointers: Most jointers (machine) now are equip- ped with an adjustment that permits of planing the edge of boards hollow in length. Demonstration: Demonstrate the matching and making of a dowel joint on a table top. Projection: Amount of projection on front and ends. Ends usu- ally will permit of more projection than front or back. Method of Fastening Tops: By means of screws through the rails. By the use of plates set in the tails and screws through the plates into the top. By the use of angle irons on inside. Not entirely desirable. By screws through strips glued and screwed along the top edge in the inside of the rail. By means of screws through buttons or blocks that fit into grooves near the top of the inside of the rail. Screw holes in strips, rails, and buttons should be slightly larger to allow for expansion and contraction. Lecture and Demonstration on Paneling Paneling: This is advisable in a large surface where there is likely to be action in the form of shrinking or swelling of wood which is caused by changes of the atmosphere. Paneling, by reason of breaking a large surface into smaller ones, takes care of this ac- tion by allowing for the shrinking and swelling in the grooves, where it does no harm to the structure. Stability and lightness: The stability of a piece of work is in- 20 creased and at the same time the weight is reduced by employing light panel work. Design of Panel: The length and width of a panel must be gov- erned by the element of design and strength. Finishing Panels: Panels should be sanded and finished before cutting the groove to receive them. Groove for panels: The groove for panel should run round all four sides of panel. Sketches and discussions: Sketches of the various methods of pan- eling and a discussion of the merits of each method should be given. Demonstration: A demonstration of the method of making a groove for a panel should be given. Lecture on Veneering Veneering: Veneering is done quite extensively. In most cases, the work looks more handsome than if solid stock were used. It is often stronger and is the more desirable construction for some classes of work. It is sometimes cheaper, and it is sometimes more expensive. This depends on the method of veneering and the kind of core. Veneer enables the more common use of rare and valuable woods for furniture than would be possible if solid stock were used. Both sides of a board should be veneered. Cross banding: In some cases, cross banding is laid under the ve- neer. This reduces and takes up the action of the core. This, together with veneer on both sides, makes a rigid piece of work that is not likely to warp or get out of shape. Thickness of Veneer: Veneer is cut as thin as 1/28" in thickness. It is kept together as it is cut from the leg and is not mixed up with other stocks as is the case with boards. The best logs only are cut into veneer. Lecture and Demonstration on Drawer Construction Clearance or play on side of drawer: One sixty-fourth to one thirty- second of an inch play on each side of a drawer is sufficient clearance. Too much clearance or play on the sides of a drawer will cause it to bind. Paraffine or bayberry wax applied to the runners and guides helps the drawer to run freely. Kind of joints: Make sketches and have models of the various joints used in drawer construction. A discussion of the merits of each joint should be given. Front: The front of a drawer may be any thickness from %" to 1" in thickness for most drawer work. In the 'case of small light drawers, however, it may be less than %". When fitted, the front of the drawer should be about 1/16" below the flush of the surface when closed. 21 Sides and back: The sides and back of a drawer may be of the same or other material than the front. In good cabinet work, however, the sides, back, and front are made from the same ma- terial. The thickness of sides and back is usually less than the front. One-half inch is sufficiently heavy for most work. Bottom of drawer: It is a good plan to make the bottom out of three-ply panel stock the top side of which is of the same mate- rial as the sides of the drawer. The bottom should be glued in front only. Friction strips: Friction strips may be set in or glued to the sides of the drawer to eliminate the friction of rubbing on the whole surface of the side. Make sketches. Fitting drawer: Drawers should be fitted before fastening down the top. Inside of drawers: When finished, drawers should receive a couple of coats of shellac on the inside to keep them clean. Hardware: Hardware should be fitted and removed before stain- ing. Drawer stops: Drawer stops may be of dowels or strips placed in front rail or at back of drawer. Des'gn of drawer: Heavy drawers are usually found near or at the bottom of a dresser or cabinet. This gives the effect of weight or balance. Period Furniture Historical: In the early days, furniture followed closely the archi- tecture of the period and developed according to the civilization, refinment, and skill of the people. Egyptian relics of furniture preserved owing to the peculiar climate of Egypt. Early furniture made of wood, bronze, and stone. Principal woods used: cedar, sycamore, and some varieties of palm. Period styles: Period furniture was usually given the name of the sovereign under whose reign the style was developed or the name of the designer. We have Louis XIII, Louis XIV, Louis XV, and "Chippendale, Happlewhite and Shearston periods. Colonial periods: This came as an outgrowth of the furniture brought over from the mother countries when America was first colonized. It was closely related to Chippendale, Shearston, and other styles. Mission styles: During the past few years, a style called mission has been developed in the United States. It has been suggested by the furniture found in the Old Spanish Missions of California. It is entirely straight line. It was at first extremely heavy and clumsy, but has now been lightened and greatly improved. Oak is the principal wood used and the color or finish is usually dark. Work similar to the Mission style is being produced in England, Germany, and Austria under the names of New Arts, Craftsman, Arts and Crafts. Very often, because of the lack of time, or the desire to get the finish on, a piece of work that may have taken many weeks to con- struct will be rushed through and slighted in the final sanding and rubbing down process. No matter how much care is taken in the staining and finishing process, it can never hide work that has been slighted in scraping and sanding. On the contrary, the staining and finishing process will magnify poor workmanship in scraping and sanding, by bringing out more clearly marks on the surface that have not been revealed in the earlier process. Scraper marks and any scratches from sanding that have been made across the grain will show very clearly. It is also true that the brighter the finish, the more clearly marks will stand out. Marks that can hardly be seen during the process of sanding stand out in relief, when the wood is given a simple oil and wax finish. It is a good plan, therefore, after the work has been sanded, to inspect it closely for such defects. The first step in the finishing state is the careful planing of all parts by hand. Very often, it is thought that the marks from machine plan- ing can be easily scraped or rubbed out by sanding. This is possible, and is always done if a belt or machine sander is used, but if the sanding is to be done by hand, such marks cannot be rubbed out. The mistake of thinking that they can be eradicated by the process of hand sanding is a common one, and is not realized until after the work has been stained. The surface of the wood prepared for staining should be free from oil, grease, or glue. It should be well dusted before staining. This lalter operation is most important, if a good finish, is to be obtained. It is one, however, that is very often slighted, and indeed, sometimes corrected altogether; such neglect leads to a cloudy or muddy finish that is very often attributed to the stain. Generally analine oil stains will be found to give satisfaction for school work. Oil stains should be given a coat of shellac before ap- plying varnish. All shellaced surfaces should be rubbed down with fine sand paper before further application is given. Filler should be allowed at least twenty-four hours to harden. A surface should be thoroughly dry and clean before receiving fur- ther applications. The room where the finishing is done should have a temperature of 70 and be free from dust. 23 LIST OF AGRICULTURAL PROBLEMS Tool chest Hammer handle Miter box Nail box Sawhorse Work bench Sawbuck Bench hook Stepladder Milk stool Neck yoke Wiffletree Wagon jack Three horse evener Wash bench Wheelbarrow Clothes stick Clothes rack Farmer's level or plumb Concrete forms Beehive Seed testing box Bird house Chicken coop Chicken feed box Trap nest Egg tester Corn rack Corn dryer Gate Sheep feeding trough Cattle rack Wagon box Hayrack Hog rack Dog house Portable hog house Road drag Tree pruner Table for milk tester or other pur- pose Hothouse Sack holder Tops Writing Tables Width 3 ft. 2 in. 3 ft. 4 in. 3 ft. 6 in.

MECHANICAL DRAWING Drawing should be given with the idea in mind of developing; visualization on the part of the pupil. This development cannot be obtained by the copying of some drawing no matter how intricate the drawing may be. Mere copying leads to superficial knowl- edge and mechanical skill instead of developing visualization, orig- inality, and self-reliance. Freehand sketching in the upper grades and especially in the high school might well receive more consideration. The principles of drawing can be taught well and quickly by means of sketching. It is also this type of drawing that is most demanded from the pupil when he leaves school. Drawing in the Grades Drawing in the seventh and eighth grades, because of the short period allowed for manual training work, cannot be given to any great extent as such. It should be sufficient, however, for the pupil to see the relation between the drawing and the project he is mak- ing. Freehand sketching on %" coordinate paper will be found, perhaps, to be the best and easiest for the pupil to develop this phase of the work. This sketching on the part of the class should consist largely of sketching the projects that they will make in UC SOUTHERN REGIONAL LIBRARY FACILITY -25- A 000051 565 o their woodwork, beginning with a simple rectangular object, such as a cutting board or plant stand as in group I of the woodwork. Drawing in the High School The work of the high school drawing may begin with freehand work on y 8 " coordinate paper. This freehand sketching may be given for the first half of the freshman year, finishing up with free- hand perspective (on coordinate paper). Freehand drawing should be made the means of rapid development of visualization on the part of the pupils at this stage of the work. A freehand lettering sheet, (preferably about 3" x 5") should be carried along with the freehand work. This should be done on plain paper ruled for about 3/16 letters. It should have but three or four lines for lettering, or sufficient for one assignment of fifteen minutes each day. The lettering may be upright gothic or inclined. If inclined, it might be well to practice upright lettering until some knowledge of lettering is obtained, and then to proceed with in- clined lettering and then lower case work. This method of letter- ing is generally conceded to give the best results. No ink work should be given in the first year except in lettering work where this practice may be taken up after some degree of skill has been obtained with pencil work. The second half of the freshman year may be devoted to the me- chanical side of the subject, if sufficient progress has been made with the freehand work. Inasmuch as all the principles of drawing have already been taught in the freehand work, the progress of this work with the instruments will be rapid. The type of problem for the beginning freehand work should be preferably some project that the pupil will be likely to make or come in contact with; boxes, stools, tabourets, tables, etc., offer good problems in their respective places. Second Year Geometrical problems: one or two plates (not more) of geomet- rical problems closely related to the shop work may be given. This can be followed by detail and assembly drawings of some small ma- chines such as lathes, grinders, small jointers, etc., and this work followed up with a few plates of cabinet and isometric drawing, followed by development work. Schools located in agricultural dis- tricts may give architectural drafting with emphasis on framing and farm buildings with modern sewage disposal facilities. Schools offering a four year course in manual arts should offer machine drawing and design and a course in architectural drafting in the third year. Students should become familiar with all phases of the industrial work offered before the end of the junior year. The fourth year should be one of specialization in which the stu- dent takes up the work that will be expected to prove the most val- uable to him after leaving school.
