THE FORESTER. 



August, 



Recent Publications. 



Mr. Gifford Pinchot's " Primer of Forestry," 

 Part I., which was reviewed in the July For- 

 ester, will shortly be issued by the U. S. De- 

 partment of Agriculture as an official docu- 

 ment. It will be published as Bulletin No. 24 

 of the Division of Forestry. A great amount 

 of interest has been displayed in the book, and 

 it is sure to be widely read . 



It is to be expected with confidence that the 

 book will quickly make its entrance into the 

 school-room and the school library, and there 

 prepare the way for its successor, "Practical 

 Forestry," and that the Primer in its complete- 

 ness will bring many fresh and enthusiastic 

 minds and hands to bear upon the forest studies 

 of their own country, which from day to day 

 are moving steadily to the front. By the time 

 the younger readers of Mr. Pinchot's book have 

 become of age, or perhaps long before, the 

 profession of forestry will, past question, offer 

 inducements which will call for many of our 

 best and most efficient men. 



The New York Agricultural Experiment 

 Station will shortly issue a circular desc; ibiDg 

 on a of the enemies of forest trees the Forest 

 Tent- Caterpillar. This insect has been abun- 

 dant this year throughout the central and east- 

 ern portions of New York. Tin caterpillars 

 resemble the common Apple-Tree tent- 

 caterpllar, except that they have a row of 

 cream white spots down the back instead of a 

 white stripe, as has the Apple-Tree tent- 

 caterpillar. They do not build a nest. They 



feed upon f he foliage of a large variety of for- 

 est trees, especially Maple, Elm and Basswood, 

 also various kinds of fruit trees. 



The caterpillars spin oblong, white co- 

 coons in anyconvenientplace, along the fences, 

 in the grass, under rubbish, on the trunks of 

 the trees or partially concealed in a leaf wtich 

 has been drawn about the cocoon. In about 

 ten days a brown moth will escape from each 

 healthy cocoon. In a few days the females lay 

 their eggs. They are placed on the smaller 

 twigs in masses, reaching nearly or quite 

 around the twig, abruptly rounded at each end 

 and covered with a glistening, frothy varnish. 

 Each mass contains about 200 eggs. The cater- 

 pillars do not come from the eggs until the 

 following Spring. 



Every healthy cocoon that is destroyed 

 means one less moth, and, as a fair percentage 

 will be females, each one of which will probably 

 lay 200 or more eggs, it is apparent that col- 

 lecting and destroying of the cocoons means a 

 decided decrease in the number of caterpillars 

 next year. 



Early in Ju'y the egg masses appear on the 

 twigs. They will show plainer when the leaves 

 are gone this Fall. While it may be impracti- 

 cable, in most cases, to collect them from the 

 forest trees, on shade trees, which are not too 

 large, they can be easily found. On fruit trees 

 it is little trouble to find them. These egg 

 masses should be searched for especially when 

 pruning the trees. Whenever found they 

 should be destroyed at once. Bulletin sent 

 free upon request.
