readers ; by C. A. Ealand. Pp. 343, with 16 plates and ]00 

 additional figures. New York, 1915 (The Century Co.). — This 

 book contains an excellent account of the relation of insects to 

 the human welfare. In it the reader will find the most important 

 facts concerning the various groups of insects as destroyers of 

 crops, as carriers of human diseases, as enemies of live stock, as 

 agencies in the control of other insects and pests, as uninvited 

 guests in the household, and as human parasites. There is also 

 an interesting discussion of the general principles of insect control. 



Tbe book, treating as it does, of the most important insects 

 without regard to their geographical distribution, will doubtless 

 prove equally valuable to students of economic entomology in 

 any part of the world. It may be cordially recommended to the 

 general readei - , for the descriptions of life histories and habits are 

 free from technicalities, many of them being not only interesting 

 but entertaining. w. E. c. 



3. Thirteenth Report on the Saraioak Museum, 1914-/ by J. C. 

 JMotjlton, Curator. Pp. 48. — This Report of the Sarawak 

 Museum gives an account of the progress on the collections in 

 the different departments. Among the Appendices may be noted 

 a catalogue of the mosquitoes of Borneo, which it is stated reach 

 the number of 92 species, of these 84 have been collected by the 

 Museum. It is interesting to be informed, though the fact is 

 regrettable, that the curator has left the Museum and joined his 

 regiment which has gone to the war. 



Obituakt. 



Dr. Joseph Austin Holmes, director of the United States 

 Bureau of Mines, died on July 13 at the age of fifty-five years. 

 He was state geologist of North Carolina from 1891 to 1904 and 

 later was engaged in the technological branch of the TJ. S. Geo- 

 logical Survey. When the Bureau of Mines was established in 

 1910, he was made the director, and from that time all his energies 

 were given to the development of this department. The results 

 attained in five years were remarkable both in the direction of 

 the conservation of the mineral resources of the countiy and, 

 still more, in that of diminishing the danger of accidents in mines 

 and saving life when these occurred. The devotion of Dr. Holmes 

 to the latter work involved much personal risk and strain to his 

 health and unhappily resulted indirectly in cutting short a life of 

 rare usefulness to the country.
