451. HoxiE, F. J. Treated lumber for insulating roofs of moist factories. American 

 Wood Preservers' Association: 1921. — Method is described of insulating a Xew J-^ngland cot- 

 ton-mill roof to prevent decay and sweating. Seven-eighths inch pine boards were treated in 

 an open concrete tank (out-of-doors) for 20 hours in creosote at a temperature of 220^F. ; 

 () lbs. of creosote was absorbed per cubic foot. The boards were applied to the old roof without 

 removing the slag or paper, on I inch sleepers, leaving an air si)ace between the slug and 

 new roof. Upon the treated new surface was placed the usual 5-ply tar paper and slag. [Paper

 of certain fungous and insect enemies of sugarcane, together with reports as to progress of 

 the investigations concerning the improvement of sugarcane by seed selection, the possi- 

 bilities of reducing the purity of the final molasses, and the condition of the soils of the various 

 sugar plantations. The forestry situation as related to sugar production and the insect 

 and disease enemies of forest trees are also considered. — J. M. Westgate.

 cophily.] Compt. Rend. Acad. Sci. Paris 172: 124-126. 1921. — This phenomenon is generally 

 attributed to gall formation due to the activitj^ of insects, but the author disagrees with this 

 as a generalization universally applicable. He finds cases especiallj^ in Acacia in which the 

 gall is apparently not to be attributed to insect activity. In some cases it has become heredi- 

 tary. The relationship when insects are present seems to be more of a parasitism than a sym- 

 biosis. — C. II. and W. K. Farr.
