The mechanical analysis of the Geneva clay loam and the sandy 
loam which were used in the soil mixtures for Crop IV, made 
by Mr. E. B. Hart, assistant chemist, from samples which were 
taken before any manure or commercial fertilizers had been added 
to them, gave the following results. The difference between the 
weight of the original sample and the sum of the weights of the 
gravel, sand, silt, clay and organic matter is here classed as un- 
settled clay and added to the weight of the clay.
