The Lepidoptera and Coleoptera take the lead in the number of 

 destructive species, and it is hard to say which works most dam- 

 age, as most of our cultivated plants appear to have enemies in 

 both ranks, though the potato and sweet-potato are especially 

 affected by beetles, and the cabbage and fruit-trees generally, by 

 caterpillars. The Hemiptera, with Phylloxera, the Chinch- bug 

 and the aphides, come next in destructive powers ; the Diptera 

 contribute several species, the Hymenoptera, though principally 

 beneficial to man, furnish him with saw-fly enemies; and the one 

 destructive locust enumerated is a host in himself. The work is 

 printed in clear type and forms in all respects an attractive volume.

U. S. Fish Commission Report for 1879. — This stout volume 

 is full of good material, whether piscicultural or zoological or 

 botanical. Several excellent papers, purely scientific and yet of 

 value in the connection in which they appear, are sandwiched in 

 between the commissioner's own report and the chapters relating 

 to fish-culture. The most important of these, and abundantly 

 illustrated with excellent wood-cuts, are Professor W. G. Farlow's 

 Marine Algae of New England, and Professor A. E. Verrill's 

 report on the Cephalopods of the north-eastern coast of America. 

 A large proportion of the volume is devoted to translations from 

 European authors, which will undoubtedly prove useful to pisci- 

 culturists in this country, though there are chapters by H. W. 

 Mason, Livingston Stone and Charles G. Atkins on the propaga- 

 tion of salmon. These reports are doing great good in both a 

 practical and scientific direction.
