variety may liave upon the variety fertilized by it, and tbat this may be 

 au important factor in experiments of tliis kind where a number of 

 varieties are grown together. 



Lettuce (pp. 10, 11). — The results of tests of thirty-eight varieties are 

 given in a table. White Tennis Ball excelled in earliness ; Black Seeded 

 Simpson, Oak Leaf, Sugar Loaf, and Versailles Cabbage in lasting qual- 

 ities ; and Black Seeded Simpson and Sugar Loaf in size. 



Potatoes (pp. 11, 12). — A table gives the results of tests of twenty- 

 four varieties. The seed potatoes were cut to single eyes and i)lanted 

 one piece in each hill. The greatest weight of crop was produced by 

 Pearl of Savoy, Early Maine, New Queen, Early Puritan, and Hamp- 

 shire County. 



ComMned fungicides and insecticides in potato groicing (pp. 12, 13). — 

 Paris green and plaster were applied on one plat, and a solution of 

 Paris green and sulphate of copper on another. ''In both plats the po- 

 tato beetle larvte were effectually destroyed. In plat No. 2 the growth 

 of foliage was slightly checked, bat the blight did not strike it quite as 

 soon as that in plat No. 1. In plat No. 1, where no sulphate of copper 

 was used, we found seventy-four rotten tubers, while in plat No. 2 only 

 sixteen rotten ones were found. This result may be accounted for i)er- 

 haps on the theory that the spores or germs of the disease were de- 

 stroyed when they reached the ground where the copper solution had 

 been retained by the soil." 



Protection of fruit-trees from mice, rabbits, and woodclmc'ks (p. 13). — The 

 exiDerience of several years has indicated that a mixture of lime, cement, 

 and Paris green in skim-milk or water is efficient for this purpose. The 

 mixture made with skim-milk adheres better than that made with water, 

 and when Avater is uf^ed Portland cement adheres more firmly than Eos- 

 lyndale. The amount of Paris green used was one tablespoonful to each 

 two gallon pailful of paint, mixed so as to easily apply with a paint 

 brush. 



Geneeal eesults of a trial of a few Japanese crops, W. P, 

 Brooks, B. S. (pp. 14-17). — The seeds were collected by Dr. Brooks in 

 Japan. The varieties tested were three of millet, Panicum crns-coroi 

 (Jap. Hiye), Setaria italica or Panicum italicum, red-headed variety 

 (Jap. Mochi awa), and Setaria italica or Panicum italicum (Jap. Awa) ; 

 and four varieties of beans, Soja beau, medium early, Olycine liispida 

 (Jai). Baidzu), Soja bean No. 2, very early, Glycine hisjiida (Jap. 

 Kuralcalce mame), red beans, Phaseolus radiatus, and white beans, 

 Phaseolus radiatus. The results of these preliminary tests were, on 

 the whole, encouraging. 



Gypsy motu (Ocneria dispar), C. H. Fernald, Ph. D. (pp. 18- 

 23). — This is a reprint of a special bulletin of this station, issued in No 

 vember, 1889, an abstract of whicli is given in Experiment Station 

 Record, Vol. I, p. 225. ^
