Page 15 - German forestry is remarkable in three ways. It has always led in scientific thoroughness, and now it is working out results with an exactness almost equal to that of the laboratory ; it has applied this scientific knowledge with the greatest technical success ; and it has solved the problem of securing through a long series of years an increasing forest output and increasing profits at the same time. Like other advanced European countries, Germany felt the pinch of wood shortage a hundred and fifty...

Page 15 - The method of management adopted calls for a sustained yield, — that is, no more wood is cut than the forest produces. Under this management the growth of the forest, and consequently the amount cut, has risen sharply. In 1830 the yield was 20 cubic feet per acre; in 1865, 24 cubic feet; in 1890, 52 cubic feet; and in 1904, 65 cubic feet.

Page 15 - If we were everywhere practising forestry with a resulting improvement equal to that made in Prussia, our forests would be growing as much as we use. The financial returns in Prussia make an even better showing. Net returns per acre in 1850 were 28 cents. In 1865 they were 72 cents; in 1900, $1.58; and in 1904, $2.50. They are now nearly ten times what they were sixty years ago, and they are increasing more rapidly than ever.

Page 15 - The yield rose 55 per cent, between 1820 and 1904, and is now 93 cubic feet per acre, — greater than that of the Prussian forests. Since the chief wood is spruce, which yields more saw timber than the average of trees making up the Prussian forests, the increase in the percentage of saw timber in Saxony naturally exceeds the increase in Prussia. It increased from 26 per cent, in 1830 to 66 per cent, in 1904.
