New YorK AGRICULTURAL EXPERIMENT STATION. 133 
Thus far the only differences to be seen in the Long Island 
fields were apparently due more to the fact that the rust got 
started earliest on the sandy lands and then drifted to the fields 
on the moraine soils. In all cases both the summer and winter 
stages were always present. Of course the fact of the rust start- 
ing on the low sandy lands may result from the influence of the 
factors set forth by Messrs. Stone and Smith. As will be shown 
further along we think a‘still different factor enters into the 
above conditions. | 
About the middle of September the writer visited the aspara- 
gus fields of the Oneida Community Limited and the surrounding 
country in Madison and Oneida Counties. He was first taken to 
a six-acre field situated in the bend of a stream, no point of 
which was over eight feet above the lowest stage of the creek. 
The surface soil of this field was called a clay loam, and was an 
alluvial deposit formed by a bend in the stream. The original 
banks of the stream consisted of a shaly clay and were some 
thirty feet higher than the asparagus field. The variety of as- 
paragus on this field was Moore’s Hybrid. The only portion of 
the field that was not entirely killed was on the tangent side of 
the bend next the original bank of the stream. This bank was 
covered with a vineyard and furnished a partial windbreak to 
the southwest of the asparagus field. 
The next field of thirteen acres was a new bed of Barr’s Mam- 
moth asparagus set the spring of 1900. It was situated a half 
mile further down the stream, to the northeast of the first field 
but on the high ground, about fifty feet above the stream. The 
soil was a clay loam with a smal] amount of gravel intermixed. 
At a distance this field appeared to be entirely free from the 
rust; closer inspection showed that it was slightly infected with 
both the summer and winter stages of the disease. The same 
conditions on newly set fields had been noted on Long Island, 
namely, that the rust did not attack them until late in Septem- 
ber, but in all such cases the fields were isolated and surrounded 
by woodland. 
A third field of ten acres was next inspected. A small stream
