Page 378 - ... and depressed in mind, that to work as a man should work is beyond his power. Hence there are often seen about employments, in this country, a number of hands double what would be required to do the same work in the same time with British labourers. The latter would probably be paid at least twice as much money per day, but in the end the work would not cost the employer more...
Page 102 - So perfect was the action of this mechanism that the fly-wheel had been wholly removed, and the engine and the whole mill-work were moving in the most smooth and effective manner. It was found that the change enabled them to give all the grinding stones a greater velocity than formerly, so that the quantity ground was greater, in the proportion of 56 to 52, and the quantity of the finest or first flour, from the same wheat, was likewise much increased ; so that, both by quantity and quality, the...

The gold was found, accompanied by other metallic substances, dispersed through a kind of stratum composed of clay, sand, gravel, and fragments of rock, and covered by soil, which sometimes attained to a very considerable depth, from twenty to fifty feet, in the bed and banks of the different streams.
Page 30 - Survey103 reported that the lowest layer of fir trees overlies 3 to 5 feet of turf ; but not so with the oaks, as their stumps are commonly found resting on the gravel or on small hillocks of gravel and sand, which so often stud the surfaces of bogs. Reade104 has shown that a railway cutting through Glazebrook moss exposed 18 feet of peat containing, in a thickness of 3 to 4 feet near the base, remains of trees and branches embedded in the peat. When the peat has been removed, one sees the oak and...
Page 30 - Reports,' such trees as are found have generally six or seven feet of compact peat under their roots, which are found standing as they grew, evidently proving the formation of peat to have been previous to the growth of the trees, a fact which in relation to firs may be verified in probably every bog in this parish, turf from three to five feet thick underlying the lowest layer of such trees.
Page 332 - Cliefden and the surrounding country were, in 1815, in such a state of seclusion, that they contributed no revenue whatever to the state ; and, up to 1822, the agriculture was so imperfect, that scarcely a stone of oats could be got. In 1836...
Page 39 - The quantity of charcoal obtained in this mode of carbonization is from 25 to 30 per cent, of the weight of dry turf. The charcoal so obtained is very light and very inflammable ; it possesses nearly the volume of the turf. It usually burns with a light flame, as the volatile matters are not totally expelled.
Page 113 - But to let alone uncertain conjectures, and to content ourselves with the Mines that are already discovered, we will in order speak of them, and begin with the Iron-mines. Of them there are three sorts in Ireland, for in some places the Oar of the Iron is drawn out of Moores and Bogs, in others it is hewen out of Rocks, and in others it is digged out of Mountains : of which three sorts the first is called Bog-mine, the other Rock-mine, and the third with several! names White-mine, Pin-mine, and Shel-mine....
Page 201 - Company," who after clearing out the old workings and driving a level a short distance into the north side of the mine, abandoned it after raising eleven tons of ore. In 1836 a lease of this mine was taken by John Taylor, Esq., of London, who commenced working it ; " The ancient workings were now completely cleared and some rude tools discovered, such as oaken shovels and iron picks, the latter of an extraordinary size and weight, also the remains of fires, which had been evidently made use of to...
Page 36 - The manner of heating of turf is, indeed, just the opposite to that of anthracite. The turf yields a vast body of volatile inflammable ingredients, which pass into the flues and chimney, and thus distribute the heat of combustion over a great space, whilst in no one point is the heat intense. Hence for all flaming fires, turf is applicable ; and in its application to boilers it is peculiarly useful, as there is no liability to that burning away of the metal, which may arise from the local intensity...
