TIO CHRISTISON—OBSERVATIONS ON 
The rate of increase seems low, but I have no other specimen 
for comparison, and, as it has steadily decreased annually, the 
tree may not be in a normal condition. As it stands, the half- 
seasons are exactly equal. June is the-best month, and the 
September proportion is above average. The best single scores 
are—April, 5; May, 25; June, 40; July, 25; August, 20; 
September, Io.

The half-season proportions agree fairly well in these two 
trees, in giving a slight preference to the second. In the 
general distribution they differ in the higher percentage of No. 5 
in the beginning of the season, and in its preferring July, while 
the other chooses June. No. 5 was much the more vigorous of 
the two, having the high average annual increase of an inch and 
three-quarters. The highest scores are all from it, except for 
September. They are—April, 10; May, 50; = 60; July 
65; August, 40; September, 15.
