Report on economic zoology for the year ending September 30, 1912, F. V. 

 Theobald {Jour. Southeast. Agr. Col. Wye, 1912, No. 21, pp. 111-221, pis. 17, 

 figs. 33). — This is the author's annual report (E. S. R., 28, p. 248) on the more

 animals injurious to fruit trees and bushes, hops, cereals, pulse, root crops,

A sealed paper carton to protect cereals from insect attack, W. B. Parker 

 {U. S. Dept. Agr. Bui. 15, pp. 8, figs. 8).— This bulletin, based upon observa- 

 tions and experiments made in California, has been summarized by the author 

 as follows: 



" Cereals may become infested before they are packed, after the packages are 

 placed in warehouses, and in the grocery stores. Insects find their way in at 

 the small holes which are usually present at the corners of unsealed packages 

 or at holes accidentally punched in the sides. Thorough sterilization at 180° 

 F. kills all insect life; and if the cereal is run from the sterilizer either through 

 a sterile cooler or directly into sterile packages and immediately sealed, it will 

 not become infested unless the package is broken. Sterilization of the knocked- 

 down cartons before packing and cleanliness with regard to the exclusion of 

 insects from the packing room will greatly facilitate the preparation of sterile 

 packages and is strongly recommended. It is absolutely necessary that all ma- 

 chinery connecting the sterilizer and the packages be free from insects. If the 

 cereal is passed through chutes or conveyors which can not be sterilized or are 

 not kept sterile, it will, through these sources, become infested even though the 

 cereal was previously sterile and was packed in sterile packages."
