OvutT-Door SILos. 
In 1887 the first out-door silo in this country was made here at 
the instance of Mr. James Wood, of Mt. Kisco, N. Y., who also 
furnished a set of the levers such as are used in England for com- 
pressing the same. An account of that first silo was published in 
the Station Report for 1887, page 73. A further account of it is 
also contained in the following statement to Mr. Wood after the 
silo was examined and completely removed : 
“The ensilage stacked in the open air in the summer of 1887 
was first opened by Mr. Plumb, September 30, and its condition at 
that time is fully described in the Sixth Annual Report, 
pp 73-75. 
“February 7 an examination of the remaining portion of the 
stack was made. The dimensions at this time being (to the cut por- 
tion) 14 x 8.5 feet by 2.5 in depth. The first foot at the top and 
about seven inches at the bottom was badly decayed, much of it 
being rotten, while the inner portion was in a condition to be 
eaten by the animals, although more or less moldy in places, 
The temperature of the interior of the stack was 108° F. The 
experiment can not be said to have been a success, but being 
opened as it was in the fall and left without further compression, 
together with the small size of the stack, were all against success. 
I have seen-ensilage fed from ordinary silos in worse condition 
than was the interior of this stack, and had it been of two or three 
times the height of this one and put up in better condition (for. 
as stated by Mr. Plumb, the timbers proved to be too light to 
admit of proper compression) I have no doubt but what the 
experiment would have been a success. . 
“The apparatus for building an open air silo was received too 
late in the summer to permit of planting out special crops for the 
experiment, and only such forage crops as were available could 
be utilized for the purpose of putting up the silo, As stated in
