Allowing nothing for waste, there are about fifty matches to the cubic inch of wood, or 86,400 to the cubic foot, making in all upwards of 230,000 cubic feet, and, as only straight-grained wood, free from knots, can be used for this purpose, the sacrifice of not less than three or four thousand well-grown pines is required for this purpose.

Sometimes Robert would stop, stand still in the middle of the room, cast a mathematical glance of survey over its cubic contents, and then dart off in another inwardly suggested direction of search. Shargar, on the other hand, appeared to rummage blindly without a notion of casting the illumination of thought upon the field of search. Yet to him fell the success.

Half a million cubic feet of the best quality of red cedar was once used annually from these Southern forests in this country, and nearly a hundred thousand feet of it was exported. A generation ago one of the world's great pencil manufacturers, L. von Faber, established a red cedar forest in Germany to see what could be done to artificially supply the demand for the vanishing wood.

"Of course not. We could not possibly allow it; could we, mother?" interposed May, with an air of relief. "I feel at the present moment we all need more cubic feet. It's so very hot; I almost think we could sit outside." And as she spoke a general move was made for the terrace, where seats and tables were arranged.

For it is easy to calculate that if there are a half million fish in Lake Michigan and each fish displaces less than five cubic inches of water there would be only two and a half million cubic inches of fish altogether lost in an expanse containing at least eight hundred billion cubic inches of water.

Ralph declared that he had been awake ever so long, endeavoring to calculate how many cubic feet of gold there would be in that mound if it were filled with the precious metal. "But as I did not know how much a cubic foot of gold is worth," said he, "and as we might find, after all, that there is only a layer of gold on top, and that all the rest is Incas' bones, I gave it up."

The greatest quantity of firewood yielded by the forests of New England to the acre is 100 cords solid measure, or 474 cubic yards; but this comprises only the trunks and larger branches. If we add the small branches and twigs, it is possible that 600 cubic yards might, in some cases, be cut on an acre. This is only one eightieth part of the quantity of peat sometimes found on the same area.

Mention the twelve principal processes employed in the cooking of food. Mention the best way in which to become familiar with the operation of a stove. Suppose that a gas meter registers 72,500 cubic feet on March 1, and that on April 1 the hand of the left dial is between 7 and 8, that of the middle dial is between 5 and 6, and that of the right dial is at 5.

His first balloon was a small parallelopiped in very thin taffeta, containing less than seventy-eight cubic inches of air. He made it rise to the roof of his apartment in November, 1782 at Avignon, where he then happened to be. Having returned some little time after to Annonay, Joseph and his brother performed the same experiment, together in the open air with perfect success.

In the flood of 1858, the delivery of the Mississippi, a little below the month of the Ohio, was 52,000 cubic yards to the second, but at Baton Rouge, though of course increased by the waters of the Arkansas, the Yazoo, and other smaller tributaries, the discharge was reduced to 46,760 cubic yards.
