Paris green, in wliich no iD.jury was done to the foliage of fruit trees, 

 grapevines, or potatoes; {'/) by the author with Paris green, London 

 pur[)le, or lime and Lonthju luirple applied to i)ear and apple trees, in 

 which it appeared that Paris green did little injury to foliage; London 

 purple alone did much injury, but this was largely prevented by the 

 addition of lime to the solution of London purple ; (.i) by two Ohio 

 fruit growers with Loudon purple for the plum curculio, in which 

 injuries by the insect were largely [)revented, but the foliage was consid- 

 erably damaged; (t) by three Ohio fruit growers with dilute whitewash 

 for the rose chafer {Macrodactylns subspinosus), with varying success;

Effects of cotton seed and cottonseed meal on the cream- 

 ing OF MILK, G. W. Curtis, M. S. A., and J. W. Carson (pp. 

 01-73). — The following experiments were made to stud}' the effect of 

 cotton seed or cotton-seed meal when fed to milch cows, on the com- 

 ])letene8s of the separation of the cream. This effect was studied in 

 cases where the cream was raised by setting the milk in Fairlamb cans 

 at 70*^ or at 45° F., and where the creaming was effected by a De Laval 

 sei)arator, each test being made with cows somewhat advanced in the 

 milking period and with others comparatively new milch. ''The selec- 

 tions of cows were made with special reference to length of time since 

 calving and to uniform individual quality as determined by previous 

 test. * * * Each animal was carefully watched throughout the 

 entire test, and at once withdrawn on the appearance of the least 

 abnormal indication, whether of appetite, general health, or condition." 



Three separate experiments were made in which the milk was set, as 

 soon as milked, in Fairlamb cans, without ice, and kept as nearly as 

 possible at a temperature of 70° F. until sour (12 to 24 hours), when it 

 was skimmed. Each of these experiments represented a different 

 stage of the lactation period. Thus the 10 cows in the first experi- 

 ment had calved 104 to 124 days, the 8 in the second experiment 88 to 

 93 days, and the 6 in the third experiment 49 to 51 days previous to 

 the beginning of the trial. In each experiment the cows were divided
