THREE FRIENDS OF HORTICULTURE. 339 



■to your society since its organization. Each year are to be found in your 

 transactions, and those of the State Board of Agriculture, valuable illustrated 

 papers on practical entomology, from his pen, which will bear a favorable 

 comparison with the ofiioial reports of most of our salaried State Entomolo- 

 gists. 



Since being connected with the college, Prof. Cook has taken spacial 

 courses of study under Drs. Louis Agassiz, H. A. Hagen, and 0. W. Ilolmes, 

 after which he received the degree of M. S., from his alma mater. 



Prof. Cook has been a voluminous writer, his articles being extensively 

 copied and well received. They are to be found principally in Rural New 

 Yorker, New York Tribune, Country Gentlman, Prairie Farmer, Colman's 

 Kural World, and the various bee journals. Valuable articles on bees and 

 economic entomology were published in the "People's Cyclopedia," and the 

 articles and lectures referred to before, as having appeared in the Michigan 

 State report, are too well known to require more than mere mention at this 

 time. But the crowning effort of his pen was his "Manual of the Apiary, 

 or Bee Keeper's Guide," of which the unprecedented number of over 14,600 

 copies have been sold since 1876. The encomiums bestowed upon it by the 

 press and qualified apiarists have been of such a character as to place the work 

 among the classics. 



Prof. Cook was married, June 30, 1870, to Mary H. Baldwin, of Dayton, 

 Ohio, two children blessing their union — B3rtie and Katie. Tne children 

 have made fine collections in oology and entomology, and Clarence Weed, 

 a rising young entomologist, has seen fit to acknowledge assistance from them. 

 Here is an illustration of a peculiar taste being transmitted through three 

 generations. 



The life of a College professor is not one to be envied, the duties b ling so 

 manifold and of such an exacting character as to permit of little time for 

 special work; yet Prof. Cook has, for more than twenty years, continuously 

 advanced his reputation as a teacher, and found time to prosecute his favorite 

 studies successfully. 



[Besides the writings referred to by Dr. Gjding, Prof. Cook has published 

 "Maple Sugar and the Sugar Bush," a very complete and fully illustrated trea- 

 tise, the only one on this subject ever published. Five thousand cipies have 

 been issued. His well known work, "Injurious Insects of Michigan," of 

 which 3,000 copies have been published, is now being revised and enlarged 

 and will soon appear. His little work, "Silo and Silage," the result of his 

 own work and experience, wa? scarce issued before 2,500 of the 3,000 

 edition was sold, and a new edition will very soon be issued. But there 

 are still more of Prof. Cook's good works, and not the least of them, 

 in behalf of Michigan pomology, which deserve mention here. He was 

 the first to prove the efficacy and safety of the use of arsenites for the 

 codlin moth : to recommend the kerosene and soap mixture, so valuable 

 as an insecticide ; and the soap and carbolic acid, now recognized as the best 

 specific against b:>rers and bark lice. All this would seem to be sufficient of 

 benefaction to his fellow men, for one man to confer; but it is not in Prof. 

 Cook's nature to rust out the latter part of a life, the pure, strong metal of 

 which has been kept so bright, and there is little doubt but that his 

 greatest work is yet to be done. — E. C. E.]
