FOODS HUMAN NUTKITION. 66 



Adults that molt in August may live over uutil the middle of the followius; 

 summer. 



As the first step toward the elimination of the tick and spotted fever, attempts 

 should be made to keep horses, mules, covfs, sheep, and dogs free from ticks in 

 order to prevent the adults from maturing and depositing eggs. It is believed 

 that this is not only feasible but a sufficient protection against the Rocky Moun- 

 tain spotted fever. 



A catalogue of the zoocecidia of Cassel and adjacent districts, H. Schulz 

 (In Festschrift dcs Tercins filr Natwrkunde zu Cassel sur Feicr seines fiinfund- 

 siehzigjahrigen Bcstehens. Cassel, 1911, pp. 96-104)- — There are listed 722

Papers on insects affecting' stored products. — Carbon tetrachlorid as a 

 substitute for carbon bisulphid ii^ fumigation against insects, F. II. Chit- 

 tenden and C. H. Popenoe {U. S. Dept. Agr., Bur. Ent. Bui. 96, pt. If, pp. Ill 

 -\-53-51). — ^The authors report 6 experiments in which infested grain was 

 fumigated with carbon tetrachlorid at strengths varying from IJ lbs. to 10 lbs. 

 to each 1,000 cu. ft. of space. 



The results show that it is not so fatal as is carbon bisulphid, and at the 

 rate of 28 cts. a pound it costs fully 3 or 4 times as much. In the case of 

 purchase at retail drug stores, it probably costs on an average 2 to 3 times as 

 much. " Considering the strength at which it is to be used, it is very obvious 

 that this chemical, unless it can be manufactured at a much lower price, can 

 not be as economically employed as a remedy for insects injurious to stored 

 products in warehouses, mills, or in any other depository, but might be used 

 for choice seeds or in office rooms and dwellings, which can be very tightly 

 closed and where the use of inflammable materials is prohibited or is for other 

 reasons undesirable."
