The possible use of hybrid poplar for intensive production of pulpwood in the United States has attracted interest during the past 20 years. Hybrid poplars represent the fruition of efforts to cross-breed most of the poplar species of the world. Developments from the first significantforest-tree-breeding project in this country are noteworthy. At this stage, factual contributions on hybrid poplar performance may best determine their place in forest practice.

This article gives the results of experiments in oak pruning, which show that decay hazard increases with wound width. It is bad practice to prune branches that will result in wounds wider that 1.5 inches. Best results will follow late dormant or early growing-season pruning, providingcare is taken in making the wound, on trees 5 inches or less in d.b.h., with the aid of a ladder and handsaw. The pruning of open-grown white oak is not recommended because of subsequent water sprouts.
