. American forestry. Forests and forestry. A Row OF Poplars Whose Branches Are Cut Back to the Trunks Every Five or Six Years to Form Nesting Sites. one or two newts of the year were to be found in practically every tree, estate of baron von berlepsch. forded them in other ways, there is good reason to hope that ultimately they can be colonized in much larger numbers than are now present under natural conditions—in numbers large enough to control, as they do in Germany, many of the injurious forest insects. For birds nesting in the branches of trees and shrubs, the pruning of certain of these after the German plan, and the planting of hedges and undergrowth in certain places, will, if German results are any criterion, eventually produce a large in- crease in nesting birds. The effectiveness of the pruning of underplanted shrubbery on the estate of Baron Von Berlepsch is little short of marvelous. In a double row hedge of thorn (Crataegus oxycantha) on the edge of a wood, the writer counted thirty-one nests of the year in a distance probably not much exceeding 300 feet, and would probably have found a pro- portionate number in the larger part still remaining, had the lateness of the hour not prevented. While awaiting the results of his pruning. Baron Von Berlepsch has found that the tying to- gether of the branches of bushes is effective as a temporary expedient. These methods, so far as known to the writer, have not as yet been given a trial in this country. One phase of this problem has thus far been unmentioned, that relating to the conservation of game birds in State forests. A detailed discussion of this. ,*.-H*' !*-? '-^^.
