“ The weather having cleared, the settlers climbed the height above Granite House. There, on the plateau, they chose a spot, well sheltered from the wind, and exposed to all the heat of the midday sun. The place was cleared, carefully weeded, and searched for insects and worms; then a bed of good earth, improved with a little lime, was made; it was surrounded by a railing; and the grain was buried in the damp earth. ”

“ Neb and Pencroft skinned them, and only brought back to Granite House their fat and skin, this skin being intended for the manufacture of boots.
The result of the hunt was this: nearly three hundred pounds of fat, all to be employed in the fabrication of candles.
The operation was extremely simple, and if it did not yield absolutely perfect results, they were at least very useful. Cyrus Harding would only have had at his disposal sulphuric acid, but by heating this acid with the neutral fatty bodies he could separate the glycerine ”

“ They must provide for their most pressing wants, settle their dwelling, and lay in a store of food; thus the cold might come upon them before the question of clothes had been settled. They must therefore make up their minds to pass this first winter without additional clothing. When the fine season came round again, they would regularly hunt those musmons which had been seen on the expedition to Mount Franklin, and the wool once collected, the engineer would know how to make it into strong warm stuff.... ”

“ But to simplify the operation, he preferred to saponify the fat by means of lime. By this he obtained a calcareous soap, easy to decompose by sulphuric acid, which precipitated the lime into the state of sulphate, and liberated the fatty acids. ”
