for Experiment Work," and (2) "Construction of Greenhouse Benches 
for Subirrigation." Side benches are objectionable and therefore it was 
advocated to divide the greenhouse space so as to have two benches 
with an alley 30 inches between them in the middle of the house, and 
a narrow one running along each side wall. For subirrigation the tile 
is laid upon the bottom of the bench and the water runs out at the 
joints, wetting the soil uniformly. If the water runs out the lower end 
of the tile too freely it may be checked by using small sheets of tin 
placed between the joints of the tile at any point where more water is 
desired in the bed. 
A plan of field experiments with fungicides was outlined by Mr. 
Halsted and some results mentioned that had been obtained during the 
present year. Spraying with Bordeaux mixture for the leaf spot of the 
beet was successful, and the anthracnose and blight of beans can be con- 
trolled. Bordeaux mixture in excess caused a dwarfing of the plants. 
A paper by Mr. Pammel upon " Bacteriosis of Ruta-bagas" was read 
by the secretary. A fatal rot of ruta-bagas was found to be due to 
microorganisms, a new species of bacillus. Mr. Mell stated that lie had 
met with a similar decay. Two other papers by Mr. Pammel were read 
by title, namely: (1) "On the Distribution of Some Weeds in the 
United States, especially Iva xanthiifolia, Lactuea scariola, Solanum 
rostratum, and S. carolinense;" (2) "Notes on Diseases of Plants at 
Ames, Iowa, 1894." 
Mr. Bolley's (North Dakota) paper upon "Effect of Change of Soil 
upon Growth of Wheat" was read by Mr. Lazenby. Among the con- 
clusions arrived at from the experiments are: (a) "That the grain or 
fruit of wheat is much less subject to variation than its vegetative 
parts; (h) that true varieties under like soil and climatic conditions 
will approximate a like product without reference to the parent soil; 
aud hence, (c) that in general the changing of seed wheats because of 
supposed advantages to be attained through change of soil is based 
upon a fallacious supposition." 
Mr. Waldron's (North Dakota) paper upon "A New Macrosporium 
Disease of Squashes" was read by the secretary, as likewise one from 
Mr. Corbett (South Dakota) upon " Determination of Sex in Shepherdia 
argentia by Bud Characters." 
Mr. Rane, of West Virginia, contributed some points upon " Surface 
Subirrigation." Ordinary tiles are used for conducting the water 
between the rows of plants. " It is simple, practical, and inexpensive."
