indicate a possible standard method of site determination and of site classi- 

 fication. In order to test the validity of the methods advocated they are 

 applied in a practical manner to a timber survey. 



Volume of western yellow pine logs from an actual mill tally, S. Bebey 

 {Jour. Forestry, 15 (1917), No. 5, pp. 615-618). — A mill tally of western yellow 

 and Jeffrey pine is here described with special reference to the application of 

 the data secured in estimating the quality of standing timber in a given area. 



The Swiss method of regulating the cut in practice, C. H. Guise (Jour. 

 Forestry, 15 (1917), No. 5, pp. 564-573).— The author used the Swiss method of 

 regulating timber cut in the preparation of working plans for two forest tracts. 

 The data secured are here given and discussed. It is believed that the results 

 secured warrant the further use of the Swiss method in regulating the cut in 

 mixed selection forests. 



Effect of depth of covering seed upon the germination and quality of 

 stock, S. B. Show (Jour. Forestry, 15 {1917), No. 5, pp. 619-623).— The results 

 are given of a series of experiments conducted at the Feather River Experiment 

 Station of the Forest Service of the U. S. Department of Agriculture on the 

 effect of depth of covering seed upon germination and quality of stock. The 

 species included in the experiment were western yellow pine, Jeffrey pine, 

 sugar pine, Douglas fir, white fir, and bigtree. With the exception of sugar 

 pine, the conclusions regarding all the species are based on spring sowing only. 

 The results secured for each species are presented in tabular form and dis- 

 cussed. 



A study of reforested chestnut cut-over land, E. C. M. Richakds {Jour. 

 Forestry, 15 {1917), No. 5, pp. 609-614). — Experiments on the reforestation of 

 chestnut cut-over land with pine transplants, here described, lead the author 

 to conclude that pine will establish itself readily on cut-over land, but that 

 chestnut and other hardwood sprouts should be cleaned out not later than 

 three years after planting the pine and this should be repeated every three 

 to five years until the pine attains a height of 12 to 15 ft. and overtops neigh- 

 boring hardwoods. 



In these plantings, which were made in New Jersey and Connecticut, chest- 

 nut blight did not kill the sprouts soon enough to prevent injury to the pine. 



Forest succession in the central E-ocky Mountains, C. G. Bates {Jour. 

 Forestry, 15 {1917), No. 5, pp. 587-592). — In this paper, which is based upon 

 general observations over a number of years in the mountainous territory of 

 Colorado and Wyoming, the author discusses different tree associations and 

 successions with the view of indicating the practical importance to the forester 

 of taking into account the systematic development of vegetation by definite 

 stages. 



The woodlot, C. A. Scott {Kansas Sta. Circ. 58 {1917), pp. 37, figs. 24). — A 

 treatise on woodlot management with special reference to conditions in Kansas. 

 A list is given of desirable trees for Kansas woodlots, including data on the 

 uses of each kind of wood and estimated yield per acre in lumber and other 

 products. A table is given showing an itemized account of the cost of growing 

 a 20-acre catalpa plantation and the returns received from it. The total expense 

 per acre for grov/ing and harvesting the plantation, which was about 16 years 

 old at the time of cutting, was $109.83. The net proceeds per acre was $152.17, 

 equivalent to an annual net income of $9.31 per acre. 



Some timely suggestions for the owners of woodlots in New England, 

 F. H. MosHEK and G. E. Clement {U. S. Dept. Ayr., Bur. Ent., 1917, pp. 8).— 

 Based on observations conducted by the Bureau of Entomology over a number 

 of years some 75 species of native and naturalized trees are here grouped into
