We cannot but congratulate Miss Ormerod upon the skilful manner in which she- 

 has accomplished her task, and we trust that her work will be fully appreciated by the 

 farmers and gardeners of Great Britain, for whose special benefit it has been produced. 

 The whole book is written in clear, simple language, free from all scientific terms and 

 technicalities so far as they can be omitted, while the modes of prevention are such as- 

 have been practically tested by competent persons, and cannot fail to be beneficial if 

 intelligently followed. We hope to see many editions of the work called for, and to learn* 

 that the aulilioress has been amply rewarded for her labour of love. — C. J. S. B. 



Reports of the U. S. Commissioner of Agriculture for 1878 and 1879. 



We have lately received copies of both of these valuable reports from the Depart- 

 ment of Agriculture at Washington. There are in them — in addition to all the other 

 useful papei*s on subjects relating to agriculture — in the reports of the Entomologist of 

 the Department, much that is of great interest to entomologists. In the report for 

 1878 we have, from the pen of C. Y. Biley, contributions on the insects injurious to the 

 cotton plant ; the silk worm, with instructions for the production of silk ; with descriptions 

 also of a number of insects injurious to fruits and field crops, occupying in all 50 pages, 

 and illustrated by seven full-page plates. In 1879, papers by J. H. Comstock on the army 

 worm, clover insects, insects injurious to the orange tree, and references to many other 

 species which injure field crops, forest and fruit trees, covering 75 pages, and illustrated 

 by six full-page plates. This volume also contains an extensive report on insects injurious- 

 to the cotton plant ; 84 pp., with 9 plates.
