We find that the temperature of both the air and soil was consid- 
erably lower during April of the present year than for April of 1886, 
while for the season just passed the rainfall for May was almost 
nothing until the very last days of the month. These two influences 
may have largely determined the growth, that is, the formation and 
number of stalks, while the higher temperature and more sunshine 
during the period of most rapid growth may have, by increasing the 
evaporation through the plant, produced the large albuminoid content 
of the grasses. When another year's records shall have been added 
to those already given it is hoped that we may be able to trace 
more fully the relation between plant growth and the variation in 
temperature, sunlight and rainfall.
