Apply with force in a fine spray, and be thorough, but do 
not continue the spray in one place until the drops run to¬ 
gether and carry the poison with them off the leaves. 
Where small patches are to be treated, a very simple method 
is to mix one pound of Paris green with about 20 pounds of 
common flour, and apply by dusting the mixture over the 
plants. This is readily done by placing a quantity of the 
poisoned flour in a small cheese cloth sack, which is held in 
the hand and shaken over the plants as the operator walks 
down the row of beets. This application can be best made 
when there is no wind and when there is a dew or rain upon 
the leaves to make the poison and flour stick.

COLORADO SUNSHINE. 
BY L. G. CARPENTER. 
The important effect of sunshine on plants, their 
growth and development, their aromatic oils, the color of 
their flowers, and the quality and color of their fruit, is well 
known. That it has an equal influence on the spirits and 
health of man, is also well recognized. In general it has a 
beneficial influence on useful plants, while destructive to in¬ 
jurious ones, as molds, fungi, and bacteria. It is one of the 
most potent germicides. Most diseases cannot spread in 
the presence of sunshine. 
The following charts showing the sunshine day by day, 
throughout two years, are of more than passing interest, 
both from an agricultural and a sanitary standpoint. The 
record is made continuously at the Experiment Station. 
The full lines show the sunshine. The breaks in the 
lines show when the sunshine was interrupted by clouds pass¬ 
ing over the sun. The diagrams show at just what hours 
the sun shone on each day of these two years. Attention 
is called to the few days without some sunshine. May was 
the rainy month in 1898. 
The record for 1897 is on one-half the scale of that of 
1898.
