The Testing Of Coniferous Tree Seeds At The School Of Forestry, Yale University, 1906-1926, James W. Toumey, Clark L. Stevens

Yale School of the Environment Bulletin Series

Quality in forest tree seed centers in (a) origin; (b) genuineness; (c) purity; and (d) viability. The purchaser should insist on knowing the origin of the seed and the locality where it was collected.

Without seed testing establishments for investigating forest tree seeds by standardized methods under an established technique, nurserymen and foresters will continue to sow seed beds and undertake direct seeding without an adequate knowledge of the origin, genuineness, purity, and viability of the seeds used.

Factors Controlling Germination And Early Survival In Oaks, Clarence F. Korstian

Yale School of the Environment Bulletin Series

There is little information available upon the seed and seedling characteristics of the American oaks. Among the fundamental problems in American silviculture, those which relate to seed efficiency are especially important. The future productiveness of the hardwood forests in which chestnut has been an important·element rests largely upon seed and sprout efficiency. Seed efficiency is governed by (I) seed production, (2) seed distribution, and (3) the factors affecting the reproductive value of the seed, such as viability, storage of seed in the litter of the forest floor, and destruction by insects and rodents.

Soil Temperature As Influenced By Forest Cover, Tsi-Tung Li

Yale School of the Environment Bulletin Series

The purpose of this investigation is to study the effect of the forest on soil temperature at definite depths, expressed in terms of daily maximum and daily minimum. By forest is meant not only the trees but the surface vegetation and litter as well. Effort was made to preserve the vegetation and litter from being disturbed over the period covered by the investigation.

Factors Determining Natural Reproduction Of Longleaf Pine On Cut-Over Lands In Lasalle Parish, Louisiana, Herman H. Chapman

Yale School of the Environment Bulletin Series

The original ' pine forests, of the southern states covered from 125 to 130 million acres of land, about two-thirds of which was Longleaf pine. Four-fifths of this area had been cut over by 1920, leaving about 230 million acres, one-half of which is Longleaf pine. Of the cut-over lands, 31 million acres have not restocked. The Longleaf pine has thus been the principal tree crop on about 85 million acres of land, of which 11% million acres remained' in 1920, giving a cut-over area of nearly 73 million acres, or 114,062 square miles. This area is nearly half the …

Boxwoods, Samuel J. Record, George A. Garratt

Yale School of the Environment Bulletin Series

True boxwood, commonly called Turkish boxwood, is derived from a small group of plants, of which the common evergreen ·box of our gardens is the type. To this group the famous botanist Linnaeus gave the generic name of Buxis, the Latin for box tree. He called the best known member of it Buxis sempervirens, which is' but another form of Ovid's "buxus perpetuo virens," the evergreen box. For long this was considered the only species, though various forms and varieties came to be recognized, several of which have since been elevated by other botanists to specific rank.

Some Effects Of Cover Over Coniferous Seedbeds In Southern New England, James W. Toumey, Ernest J. Neethling

Yale School of the Environment Bulletin Series

The object of the study as at first conceived was to secure experimental data under the climatic conditions of southern Connecticut: 1. On the effect of shade as compared with full light on the time required for germination, and on germination values in representative conifers, and on survival and growth during the first season. 2. On the effect of mulch as compared with exposed soil on the time required for germination, and on germination values in representative conifers, and on survival and growth during the first season.

Cocobolo, Samuel J. Record, George A. Garratt

Yale School of the Environment Bulletin Series

Cocobolo is a valuable timber of commerce that has been in use in this country, particularly for handles of cutlery, for more than fifty years. It is produced by certain species of Dalbergia indigenous to Central America and southwestern Mexico. The present commercial sources are Panama, Costa Rica, and Nicaragua.

Lignum-Vitae: A Study Of The Woods Of The Zygophyllaceae With Reference To The True Lignum-Vitae Of Commerce--Its Sources, Properties, Uses, And Substitutes, Samuel J. Record

Yale School of the Environment Bulletin Series

The true lignum-vitae of commerce belongs to the family Zygophyllaceae, of which only three genera, namely, Guaiacum, Porlieria, and Bulnesia, have representatives of tree size, and these are confined to the tropical and sub-tropical regions of the Western Hemisphere. Porlieria is of no commerical importance.

In 1913 the Yale School of Forestry came into possession of certain parcels of land located near Keene, New Hampshire. This land amounting to 629.4 acres was presented to the School as a nucleus for a school forest to be used for purposes of instruction and research. Subsequently in March, 1915, additional lots comprising 270.9 acres were purchased with funds contributed by the original donor. The present area totals 900.3 acres and is know as the "Keene Forest."

A Classification For Forestry Literature, Faculty Of The Yale Forest School

Yale School of the Environment Bulletin Series

The following classification for forestry literature has been prepared by the Faculty of the Yale Forest School for use in its library. It is published to supply the demand for a simple and comprehensive classification that is adapted to any library system. The work was begun about one year ago and included a study of all available data on the subject. A tentative outline was submitted to prominent members of the profession from whom helpful suggestions were received.

The subject has been divided into nine parts of approximately equal importance. The secondary divisions also have been limited to nine and …
