Page 112 - ... one hundred and thirty tons, leaving nothing in the bottom but a few small veins. Upon these we sank our shaft, and at a depth of fifteen feet, making in all thirty feet from surface, we intersected pocket No. 2, immediately underneath the first deposit and making in the same direction. The manganese in the second pocket is of far superior quality to that found nearer the surface, and we have returned from it some hundred and eighty tons.
Page 120 - ... so as to prevent the reduced quartz from filling the holes in the false bottom. Muriatic acid should then be added if manganese alone is used, and diluted sulphuric acid if manganese and salt have been employed, and, after having left the whole in contact for twelve hours, water should be added so as to fill up the whole space between the false and true bottoms with fluid. This fluid should then be pumped up and allowed to percolate through the mass, and after this has been done several times,...
Page 196 - The water however is remarkably efficacious in curing cutaneous complaints or eruptions. In my own opinion the Wilmot springs deserve to be better known and more frequented than they are at present. If the proprietors were men of substance and energy, I have not a doubt but that their locality would be one of the best known places in all Nova Scotia.
Page 44 - ... quartz veins and the alluvial deposits derived from these and the surrounding rocks, but also in the claystone itself, and, contrary to expectation, flat bands of auriferous quartz have been discovered in dykes of diorite which intersect the Upper Silurian or Lower Devonian rocks. Quartz of extraordinary richness has been obtained from these bands, and the new experience of the miner is leading him to look for gold in places heretofore entirely neglected.
Page 192 - Breton. — This water has an extraordinary and apparently well grounded reputation for procuring alleviations and effecting cures in various maladies, authentic cases being known of much, benefit resulting from its use in rheumatism and severe headaches. A gentleman of high standing and of scientific reputation informed me that he had obtained a good appetite and increased strength by taking about five gallons of it, and by further use a moderation of the violence of asthmatic attacks to which he...
Page 80 - ... of sodium to the acid mixture, will decompose any silicates which may remain, and volatilize the silica present. The mass is now washed with abundance of water, dried, and heated to redness. This last operation causes the grains of plumbago to exfoliate, and the mass swells up in a surprising...
Page 86 - ... deviation is much smaller ; and in general there is an approach to parallelism between the course of the vein and that of the rock formation of the hills, as well as that of the junction of the carboniferous and metamorphic systems. The vein for a space of seven miles along the hills is always found at distances of from 300 yards to one-third of a mile northward of the last carboniferous beds, and always in the same band of slate and quartzite. Westward of the Acadia Mine, the course of the vein...
Page 29 - Practically it will be found to be a serviceable coal for domestic fires, well adapted for smith's use, and, from the large quantity and high illuminating power of its gaseous matter, probably a good gas coal. There should be little waste in its extraction, and it will suffer little by being banked or kept in the open air.
Page 124 - ... in the air, and even in water only superficially ; their white colour is of a shade between steel and silver. Alloys of copper and manganese are similarly obtained ; they resemble bronze, but are much harder and more durable. Alloys of tin are very fusible, durable, and easy to work ; in colour and brilliancy they may be compared to silver. The iron and manganese alloy furnishes a very simple means of adding to iron or steel a given amount of manganese ; by the addition of from no to 5 per cent,...
Page 85 - ... ankerite is intimately mixed with crystals and veinlets of yellowish spathose iron. The red ochrey iron ore occurs in minor veins and irregular masses dispersed in the ankerite. Some of these veins are two yards in thickness ; and the shapeless masses are often of much larger dimensions. Specular iron ore also occurs in small irregular veins, and in disseminated crystals and nests. At one part of the bank there appears to be a considerable mass of magnetic iron ore, mixed with specular ore ;...
