Reports of the U. S. Commissioner of Agriculture for 1878 and 18'jg : 



We have lately received copies of both of these valuable reports from 

 the Department of Agriculture at Washington. There are in them, in 

 addition to all the other useful papers on subjects relating to agriculture in 

 the reports of the Entomologist of the Dept, much that is of great inter- 

 est to Entomologists. In the report for 1878 we have, from the pen of 

 C. V. Riley, Contributions on the Insects Injurious to the Cotton Plant ; 

 the Silk Worm, with Instructions for the Production of Silk ; with descrip- 

 tions also of a number of insects injurious to field crops and fruits, occu- 

 pying in all fifty pages, and illustrated by seven full-page plates. In 

 1879, papers by J. H. Comstock on the Army Worm, Clover Insects, 

 Insects Injurious to Orange Trees, and many other species which injure 

 field crops, fruit and forest trees, occupying in all 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. 



Ottaiua Field Naturalists^ Club : 



The second volume of the transactions of this active body of natural- 

 ists is at hand. It is a neat pamphlet of 44 'pages, 8vo., with one excellent 

 plate illustrating a new species of Porocrinus from the Trenton lime stone, 

 accompanied by a description, with some remarks on the genus by Dr. 

 James Grant. In addition to the annual report of the Club, the volume 

 contains the inaugural address of the talented President, James Fletcher, 

 Esq.; a paper "On some Coleoptera Injurious to our Pines," by W. H. 

 Harrington ; one by Prof J. Macoun, " On the Capabilities of the Prairie 

 Lands of the Great North-west, as shown by their Fauna and Flora," and 

 other interesting contributions. We congratulate our Ottawa friends on 

 the good work they have done this year, and sincerely hope that their 

 active efforts may have the effect of promoting a general love for natural 

 history among the residents of the capital of our Dominion.
