The peculiarity of the plant growing of the season has been the 
luxuriant growth of the foliage, especially marked in the Cucurbit- 
aceous plants and in tomatoes. What the relative influences towards 
this result of moisture, temperature, or actinism must remain un- 
known until our records are more complete. 
Our soil thermometers were placed in the ground on April 10, but 
were maliciously destroyed during the night of April 20. We were 
unable to procure new instruments until June 12, and these were for 
a different depth than those heretofore in use, a matter of regret, as 
also the break in our records. 
That the one factor of temperature alone is insufficient for the pur- 
pose of noting the relations of climate to growth may be illustrated 
by two varieties of corn, the one early the other late, noting the days 
between vegetation and bloom, and the sum of the mean tempera- 
tures of each day during this interval. It will be seen that while 
the earlier variety required more heat units in 1885, the later va- 
riety required less. |

The explanation of such discrepancies as shown in the above tab- 
ular statement may be looked for in actinic records, had such been 
kept during the years preceding the present, but the most import- 
ant use of these figures is to call attention to the necessity of careful 
and scientific meteorological and climatic studies as an aid to enable 
us to predict from local studies of plant growth and cropping what 
may be expected to occur in other regions whose climatic conditions 
are known. 
The lysimeter records have been kept as usual during the year. 
The value of these observations must arise through the length of 
their continuance, and hence we shall postpone their discussion un- 
til a later date. When these records are discussed, the results will 
doubtless prove of value as throwing some light upon the subject of 
nitrification within. the soil, but the influence of cultivation upon the 
checking of evaporative changes in the soil can at present be readily 
read from the figures which are given in the chemist’s report.
