No excava- tions or blasting of the rocks was porniitted by the owner of the mine, so I was obliged to content myself with such sur- face explorations as could be made without sinking ui)on the lode, t oing the outcrop along its course from one exposure to another, and measuring the (h[) of the vein, and computing its underground situation and the method of opening upon it. At one point, near the road-side, some excavation had been made, and there the dip of the strata of rock and of the vein of copper-bearing quartic was ascertained. This point is 1070 feet distant in a N. E. course from the outcrop on the hill; and it in evident Ihat the vein is continuous from one of these places to the (jther, though at the road-side the vein measures only eigh*^ inches in width on tiio surface, and wi- dens s(jmewhat as it descends into the rock. The dip of the strata of slale and of the vein is to the north-west and 40*^ from the hori/on. The ores disclosed at this opening arc, green carbonate, red oxide, ferruginous black oxide, gray sulphurct of copper, and yellow copper pyrites. They occur in the ([uartz vein, associated with brown spar, or carbonate of iron. At the cob-houso, on the hill, the vein is three feet wide, and is much richer in copper cres. Large (piantities of car- bonate of copper also exist in the soil, and in the decomposed parts of the vein. Gray copper ore is the i)rinci{ial and most valuable ore exposed at this place, and it oc( urs in awrh pro- l)ortions as to render the vein valuable as a copper ore, masses of pure and solid ore, large as a man's iist, being readily obtained. This vein has been traced from point to point in a direction N. E. and S. W. fntiu this place, about two and a half miles, one mile of which is on the lot now ollered for sale. The lot consists of 100 acres, and is one-sixth of a mile wide. ♦ From the outcrop on the hill, at the cob-honso, T found the land to slope north-wost to the fence 10° 1(1': dis- tance 113 foot. From theiico to tho lowest land the slope is 14" 1'; distance 100 feet. The vein dips to tlio north-west 40°, and hence is buried deep at the base of the hill, as shown by the accompanying diagram, which e ibits the lay of the land, the dip of the vein, and the method of opening upon it by shafts and an adit level. It is obvious that a large por- tion of the vein may be commanded by very simple mining operations, and if the ore proves as rich under ground as it is on the surface, it cannot fail to prove valuable, for a sheet of the vein a mile long, and probably two foot in average thick- ness, and of any depth opened, will be accessible to the miners who will sink a series of pits and drive levels on the lode, if the mine is wrought in the usual manner.

Outcrop. i it 5 ch 3 f Before sinking regular shafts, it will bo proper to open the outcrop to sufHcicnt depth to ascertain the cxuct dip, and also the value of the lode. This jjroliinfnary operation w:ll fur- nish such information as will enable the minors to learn whether there is a probability or not thai the mine will prove a p.^ying one, and will decide the question as to work- ing it on an extensive scale, or not to work it at all ; for no man can now, from inspection oi" a mere outcrop, decide those questions with certainty. The (Question now is one of probabilities, and it is proper to state that the Leeds Copper ]\line is in the same " country" or rock, in the same kind of gangue, and the ores are v>f the same kinds as those of the Halifax Mine ; and I understand that the Leeds IVmo is a per- manent ">ne, and is wrought [irofitably, the ore being sent to Kngiand. Its shafts are 37 fathoms deep, and there is an adit level 220 fathoms long. The Chester Mine is of the same nature, in the same kind of rocks and gangue, and thus far gives promise, as I am told, of being a profitable mine, though it has been but recently opened. EXPENSE OF SENDING THE ORE TO MAKKET. It was ascertained, by inquiry of the " habitants," that the ore from the Halifax Mine can be hauled to Stanfold on the frozen Ni ollet River in winter, for $5 per ton, and that it will then cost $6 per ton to take it to Boston by railroad, making the whole cost of transportation at $11 per ton. This is a very reasonable freight for ore which may bo dressed so high as that of the Ilaliiax iMine, it being the rich gray copper ore chiefly. This ore will smelt easily with that from Ac;ton, the latter holding a mixture of lime rock, which will llux the quartz of the Halifax ore. It will be more economical to send the ore, properly cleaned, to Boston or Now York, than smelt it on the spot, and there is less land transportation of the ore from the Halifax Mine to the railway than is rcipiired by the Leeds Mine. The latter requires 33 miles of hauling in wagons liy horsoH. 6 nUILDINGS ON THE LAND. The '.''oods liavc been cleared oft" and the stninps removed from the chief part of the land, and two small houses and two barns are now upon it, and these, it is understood, are to be sold with the mine. LAIJOU FOR MINING AND OTHER WORK may be had at unusually low rates, the French people in the county all around seeking such employment, and working at low wages. A few regularly educated miners will bo required, of course, but the chief labor will be performed by the French " habitants," who become, under instruction, good miners. WATER FOR DRESSING THE ORE. A never-failing stream of water passes close to the mine, and will furnish all the water refpiired, both*for steam engines and washing machinery. It may also, by means of a dam, bo made to give adeciuate water-power for driving stamps or for crushing the ore. This water-power, 1 understand, will belong to the ])rop- erty, and adds to its value, since it aids in aniinporiant way in concentrating the ores, by furnishing adequate power and an abundance of water for that purpose. ANALYSTS OP THE HALIFAX GRAY COPPER ORE. A sample of the gray ore, picked as dean from the rock as possible, yielded on chemical analysis of 100 grains, — Metallic copper . Silicious matter . yulphur and iron 57.0 ().G 30.4 100.0 Black oxido of copper, according to authorities, yields per cent.,— "" ' Copper Oxygen 79.86 20.13 100.00 Ture red or sub-oxide of copper contains, per cent., - ^°PP«^ • •' ... . 88.88 Oxjgen . . . ^ . ^ 1112 100.00 Copper pyrites contains 34 per cent, of copper, and the green carbonate 55 per cent.>. In dressing the ores by water, only the gray copper ore, copper pyrites, and perhaps •orne of the red oxide, can be saved. The value of a ton of copper ore is ascertained, at tho price now paid, by multiplying tlie percentage yield by four dollars ; hence, in estimating the value of tho gray ore, as analyzed, we have 57 X 4 = $228 as its market value. It should, however, be observed, that it will not be economical to dress the ore so high, on account of the loss of the por- tions which will adhere to the gangue, and that it is not desirable to raise it higher than 20 per cent., which will be a sufficiently rich and marketable ore.
