"Matured," and "Days to mature' apply only to the planting up to and including the date in the first column. The items in the other columns apply to the whole piece.

The per cent of corn standing and that taken by squirrels was made from actual daily counts of hills.

In computing the yield the corn was weighed instead of measured.

Experiments of 1888 in planting corn at Brookings, S. Dak.

"I regret not to be able to state the source whence the seed was obtained and the climatic peculiarities under which it was raised. According to Linsser's laws this must decide as to the behavior of the seed and plant in a new climate. I know, however, that some of the varieties had been raised in previous years in the neighborhood of Brookings, S. Dak.-C. A.

In comparing the maize experiments at Brookings with the climate of that region, I shall use the record of the Signal Service station at Huron, S. Dak. (lat. 44.3° N.; long. 98.1° W.; altitude above sea level, 1,300 feet), which is 70 miles west of Brookings, and the general meteorological tables for Huron as calculated for this agricultural usage are appended to this table of agricultural experiments.
