 sects injurious to pastures. 



Mr. F. M. Webster reported last year upon the development of the 

 Hessian Fly, indicating the desirability of late sowing as a means of 

 lessening the fall attack. He has found the present season that where 

 this late sowing is practiced a procrastination in preparing the ground 

 for seeding leads to the development of other injurious insects, viz, the 

 larvae of certain Crane-flies upon which he reports this year in full. 

 He recommends plowing in the latter part of August or the early part 

 of September, and refraining from seeding until later. 



Prof. A. J. Cook, who was temporarily in charge of the experiments 

 in Apiculture, reports upon a series of investigations which he car- 

 ried out during the season with the help of Mr. J. H. Larrabee. 



Mr. Samuel Henshaw has been engaged chiefly in work on the bibli- 

 ography of economic entomology, but was requested to make some 

 observations on the Gypsy Moth, and the report on that insect and on 

 the work being done against it by the State of Massachusetts is also 

 included.
