The Moneymaker trees were budded in 1918 on the old Frotscher 
stock, and there is no dead-wood record for this variety. The annual 
girth growth and the yields of both the Frotscher and the Money- 
maker trees are given in Table 7.

1 Trees showing no indication of rosette. 
The quantity of dead wood cut from the orchard was very great in 
1917, 1918. and 1919, which is a good measure of the prevalence of 
rosette. This decreased greatly in 1921 and diminished to a very 
small amount in 1922. Id 1923 there was almost no rosette, show- 
ing that the orchard had apparently overcome the disease. The 
trees grew slowly prior to 1918, but made a more rapid growth 
the followiDg four years, or after the rosette began to decline. 
In 1918 and prior to that year the orchard yielded few or no nuts. 
The yields have increased under the treatment given the orchard, 
and in 1923 the Frotscher trees yielded 576 pounds and the Money- 
maker trees 530 pounds per acre.
