tions can be made between the producer 

 and consumer. The Chinese dealers want 

 a guarantee of a constant supply. They 

 are not willing to accept one consignment, 

 but demand that they be assured of con- 

 tinuous supply, even though it be small. 

 An American formerly in the service of 

 the Philippine Government, now in busi- 

 ness in Shanghai, reports that there is a 

 demand there for Philippine lumber, but 

 there is not a constant supply, and the 

 purchaser is never sure of getting enough 

 of the same class to complete his particular 

 job.

The Zimmerman Pine Moth, By Josef 

 Brunner. U. S. Dept. Agri. Bull. 295. 

 12 pp. XI pis. Washington, D. C, Oct. 

 28, 1915. 



For years this insect was known as an 

 enemy of pine in the east. More re- 

 cently it was found by the forest ento- 

 mologists to be a rather serious enemy of 

 second-growth pine, especially yellow pine, 

 also in the west. While of secondary im- 

 portance economically, it is largely a 

 primary insect physiologically as regards 

 the trees it attacks. From the stand- 

 point of pure science the life history of 

 any insect is capable of yielding facts that 

 may shed light on hitherto obscure 

 points in one or more phases of general 

 biology. From the economic standpoint 

 we have had repeated occasion to be im- 

 pressed with the importance of knowing 

 everything possible about the seasonal 

 and life history of all insects having an 

 economic bearing, however small this role 

 may be, as the only means of discovering 

 available opportunities for combating 

 them if they are injurious or utilizing their 

 services if they are beneficial. The paper 

 before us is another illustration pointing 

 to the emphasis to be laid on as nearly 

 complete a knowledge as possible of the 

 habits of an injurious insect. The Zim- 

 merman pine moth, the author demon- 

 states, is most injurious to second growth 

 on which we would apparently be utterly 

 helpless in combating it under forest con- 

 ditions where the use of insecticides is 

 out of the question. But his careful two- 

 year study of the insect showed that it 

 inhabits dominantly also some old light- 

 ning-struck or gnarly branched trees left 

 standing in the midst of old clearings. 

 These trees serve the moth largely as 

 "brood trees," as the author calls them, 

 and thus to stock the area with it. It 

 becomes perfectly patent, therefore, that 

 the removal of such brood trees should 

 practically eliminate the insect as a 

 serious pest. The actual experiment cited 

 shows this conclusion to be operative in 

 practice, and the recommendation is made 

 accordingly. J. K. 



"I have just had an opportunity to look 

 over the numbers of American Forestry 

 which have been issued during my absence 

 in Alaska. I write this to tell you how 

 delighted I am with the new form of 

 American Forestry, and to ofier you my 

 congratulations. The new magazine is ex- 

 ceedingly attractive, far more so than the 

 old form; it is dignified, and offers a far 

 better opportunity than previously to 

 reach the reading public. Every member 

 of the Association should be proud of the 

 magazine, and there is due to you great 

 commendation and credit for the way you 

 are handling it." 



Henry S. Graves, Chief Forester, 

 Washington, D. C. 



"May I heartily congratulate you on the 

 magazine's new dress. It is most motish 

 and intensely interesting and a joy to the 

 eye." 



Stanley Clisby Arthur,

 the excellent new form and appearance of

"The enlarged edition of American For- 

 estry to hand. Allow me to congratulate 

 you on the new issue. I sincerely trust it 

 may increase in circulation and recompense 

 you for your efforts to place before the 

 public such instructive and excellent litera- 

 ture. Wishing you every success, I am" 

 Sister Mary Aloysius, Directress, 

 Convent of Mercy, Plymouth, Pa. 



"I cannot refrain from expressing my 

 admiration for American Forestry in its 

 new form the magazine is a gem and I 

 have no doubt that the great educational 

 work in which you are engaged, and which 

 has already accomplished so much, will 

 receive a greater stimulus from now on." 

 WiHARD Fracker, 

 Washington, D. C. 



"Congratulations on the new form of 

 American Forestry. This new number is 

 mighty fine and I am sure will not only 

 please the present subscribers but will 

 mtan large additions to your subscription 

 list. As my brother, Ray Stannard Baker, 

 has had a good deal to do with the making 

 of the American Magazine, I have fol- 

 lowed with a great deal of interest the 

 development of some of the magazines of 

 this country. Your change is in line with 

 the changes which the American Magazine 

 made earlier and which McClure's, Hearst's 

 and others have made more recently. With 

 lots of good wishes for the new magazine 

 as it really is, " 



Hugh P. Baker, 



Dean, New York State College of For- 

 estry, Syracuse, N. Y. 



"Kindly allow me to congratulate you on 

 the August issue of American Forestry. 

 It is a credit to you and to your associates, 

 and I hope that the time will come when 

 you can boast of a much larger circulation. 

 You are particularly fortunate in being 

 able to start a Wood Preserving Depart- 

 ment and more especially in being able to 

 have Mr. Sterling handle it." 



C. M. Taylor, 

 Superintendent, Port Reading Creosoting 

 Plant, Port Reading, N. J.

 gust number of the American Forestry,

"Have received American Forestry for 

 August, containing the article relative to 

 'How Switzerland Cultivates Her Forests,' 

 and take this opportunity of compliment- 

 ing you upon the splendid manner in which 

 you have published this contribution." 



M. DOSSENBACH, 



New York City. 



"I am sure you are getting a great many 

 letters of congratulation upon the fine ap- 

 pearance and excellent quality of the Au- 

 gust number of American Forestry. I 

 hope there are many applications for mem- 

 bership in the Association coming also. 

 Permit me to add my Httle word of praise 

 and appreciation, and to say that I have 

 noted the steady improvement in American 

 Forestry for many months, but look upon 

 the new departure as a kangaroo leap for- 

 ward for conservation."

 sociation, Swiftwater, Pa.

 should be increased interest in the maga- 

 zine now that you are able to give better 

 illustrations. The Department idea is 

 good." Prof. Ralph S. Hosmer,

 lege of Agriculture at Cornell Uni-
