The questiou of deep versus shallow planting of peas was tested by drilling in 

 one row about an inch deep with the Planet, jr., drill, another row being sowed 

 in a trench and covered 4 inches deep. The result showed that the deep-planted peas 

 came up first, and were ready for market two days before the others. There was no 

 perceptible difference in the yield. 



Varieties of sugar beefs. — Several varieties of sugar beets aud of the 

 common blood beet were grown and analyzed at tlie Station. The 

 yield varied from 219 to 482 bushels per acre and the sugar from 9.67 

 to 12.25 per cent. 



Japanese veffetahles. — A laige number of varieties of vegetables, in- 

 cluding beans, eabbages, radishes, and egg-plants, received from Prof. 

 C. C. Georgeson, Tokio, Japan, were tested in the field, but the results 

 this season were unsatisfactory. Experiments with them will be con- 

 tinued.

The Botanical Department (p. 3). — This article contains a plan 

 and brief description of the rooms and appliances of the botanical de- 

 partment of the Station. " The general laboratory is especially fitted 

 for research in vegetable physiology." " The bacteria room has an 

 excellent outfit for the study of microbes." " A greenhouse will shortly 

 be added." 



Spotting of peaches and cucumbers, J. C. Arthur, D. Sc. 

 (pp. 5-10), (illustrated). — This article contains an account of the fungus 

 {Cladosporinm carpophihim Thuem.) to which is due the spot disease of 

 peaches common in Indiana and which " in some seasons causes a loss 

 of as much as 10 per cent of the value of the crop." This fungus has 

 hitherto only been recorded as occurring in Southern Austria. There 

 is also an account of the closely related fungus which caused the spot 

 disease of cucumbers at Geneva, N. Y., in 1887 (see report of New York 

 State Experiment Station for 1887, p. 316). This disease disfigures 

 the fruit so as to render it unsuitable for pickling, though its flavor is 

 not affected. The name proposed for this fungus by Dr. Arthur aud 

 Mr. J. B. Ellis, of New Jersey, who has also examined it, is Cladospo- 

 rium cucumerinum, Ellis & Artfiur. No remedies for either of these 

 fungi have yet been tried.

Cross-fertilization of clirysanthemums. — This article contains a record 

 of the methods used and the results attained in an attempt to produce 

 new varieties of chrysanthemums. The results as detailed in the tables 

 given in the bulletin are thus summarized : 



(1) That fertilization by means of i^oUen from the same stock does not give any de- 

 cided variation of color, and that crossing is an absolute necessity for the production 

 of varieties distinct in color.
