NEW PUBLICATIONS. 



Ojitlines of Efitomology. By Mary E. Murtfeldt. Svo, pp. 135. 

 Published by the author, Kirkwood, Mo. 

 This work was originally prepared at the request of the State 

 Board of Agriculture of Missouri and embodied in its proceed- 

 ings, but the author has had copies bound and offers them for 

 sale at fifty cents each. It is a delightful book and one that is 

 simple, easily understood and therefore attractive. It has been 

 prepared by a wn'iter learned in her specialty and one who has 

 justly earned an enviable reputation. Primaril}^ prepared for the 

 use of farmers and horticulturists to teach them to recognize their 

 friends and enemies among the insects, it contains much that is 

 of interest to every intelligent person fond of the out-of-doors 

 world. The author has written the book remembering, as she 

 says, " that there are those who have yet to learn the difference 

 between a beetle and a bug, or between a moth and a butterfly ; 

 to whom the transformations of insects ofier a puzzle which they 

 cannot solve, and who are completely daunted and discouraged 

 by a half dozen successive technical terms." Miss Murtfeldt has 

 prepared a little treatise which can be cordially commended to 

 any one having the least interest in the subject.
