~The object of the experiments herein described was, in the main, similar 
‘to that of the lysimeter experiments previously reported by the authors, 
the essential differences being that a soil of another series was used, and 
that the effect of different cropping systems on the removal of the soil 
eonstituerits in the drainage water was not a feature of the present 
experiment. The lysimeter tanks were like those described in the earlier 
publication. 
| THE SOIL USED 
The tanks were filled in the summer of 1910 with a soil classified by the 
United States Bureau of Soils as Volusia silt loam. The soil is typical 
of much of the hill land of southern New York. It was formed, in the 
main, from shale and sandstone as the result of glaciation, which was 
rather feeble on these high lands. There is much broken shale distrib- 
uted thru the soil, the pieces varying in size from small particles to large 
rocks. The subsoil is often very compact, and even on the hillsides poor 
drainage is the rule. The soil layer is often shallow on the hills, the shale 
in some places lying three or four ‘feet below the surface. 
In chemical composition this soil is distinguished by its low content of 
ealcium. The other soil constituents are present in what may be con- 
sidered fairly liberal quantities. Agriculturally Volusia silt loam ranks 
‘as poor, and the sample placed in these lysimeter tanks is considerably 
less productive than the average soil of the type. It is a much less pro- 
ductive soil than the Dunkirk clay loam contained in tanks 1 to 12. Its 
low productivity as a type may be due in part to its location, which is 
mainly on high elevations, the approaches to which are steep, making it 
inaccessible to railroads and thus adding to the difficulty of applying lime 
and fertilizers, which have consequently been meagerly used on these lands.

| AcKNoWLEDGMENT.— The authors wish to express their thanks to Mr. E. W. Leland for his services 
in measuring and sampling the drainage water during the entire period of the experiments, and for super- 
yising the cultural operations on the tanks.
