This is the seventh report on a series of studies to show the relationship of stump diameter to diameter breast high (d. b. h.) for commercially important tree species in the Northeast. This report is for pitch pine (Pinus rigida).

This is the eighth report on a series of studies to show the relationship of stump diameter to diameter breast high (d.b.h.) for commercially important tree species in the Northeast. This report is for white oak (Quercus alba).

The presence of red rot (Fomes pini) in pruned white pine stands has often been attributed to the act of pruning. This assumption may well be true for heavily stocked stands where thinning has been neglected and pruning scars are slow to heal. The question then arises: How do we account for the red rot often found in vigorous unpruned white pine stands? Evidence collected in connection with a white pine log-grade study at the Pack Demonstration Forest at Warrensburg, N.Y., strongly suggests that the white pine weevil was responsible for much of the red rot found in the trees examined.

As individual eastern white pine trees grow taller, are they less susceptible to attack by the white pineweevil? At what height are they most likely to be attacked?

The amount of hardwood planting stock used in forest tree plantations in the United States is very small indeed. The great bulk of planting stock used is softwood. Wallihan (4) points out that there are several good reasons for this. First of all is the greater demand for softwood forest products. Another is the fact, often demonstrated in the past, that softwoods are much easier to establish than hardwoods. It is also well known that volume (but not necessarily value) yields from hardwood forests are considerably lower than those from softwood stands. As a result, the culture of hardwoods...

Though the "cord" is used as a standard unit of measure for stacked wood, there is much confusion as to what a cord is and how it can be properly converted to other units of measure. The amount of solid wood in a pile varies greatly depending on the size, straightness, and evenness of the material in the pile, and also on the closeness of stacking.

This is a report on the first comprehensive survey ever made of the timber resources of Rhode Island. It shows, for the years 1952 and 1953, the area and condition of the forest land, the volume and quality of standing timber, the rates of timber growth and mortality, and the extent of timber cutting for forest products. The survey was made by the Forest Service as part of a nationwide survey of timber resources. NOTE: this document was scanned from a personal copy and contains hand-written notes.

Skidding is often an expensive operation. This is especially true in mountainous country where the terrain is difficult and skidding distances are usually long.

It has now been over half a century since chestnut blight, caused by the fungus Endothia parasitica (Murr.) A. & A., was introduced into America from the Orient. In that time the blight has spread relentlessly and has destroyed all of our commercial stands of this once most valuable hardwood species of the East.

This is a report on the first comprehensive survey made of the forest resource in Connecticut. It shows the area and condition of the forest land and the volume and quality of standing timber as of January 1, 1953, and the annual growth and mortality of the forest growing stock, and the extent of timber cutting in 1952. The survey was made by the Forest Service, U.S. Department of Agriculture, as part of a nationwide survey of timber resources.
