to secure a close estimate of the coming crop, so that barrels may be 
provided. It might appear that the taking of notes on each tree in a 40-acre 
orchard would be a tremendous job, but it proves to be very little trouble. 
A set of small, pocket note books is used, a page to each tree. It has not 
been found necessary to mark or tag the trees in order to designate them by 
number; the note book starts with row 1, tree 1, and goes on to tree 54 
at the end of the row, then back to row 2, tree 1, and so on. Following is 
a sample record:

The figures are the estimated number of barrels of apples on the tree 
that year; the cross refers to the condition of the tree, single cross indicating 
lack of vigor, and a double cross decided lack of vigor. Trees showing 
conspicuous lack of vigor and unproductiveness are marked at this time 
with a strip of cheese cloth tied to a limb or spotted with white paint. 
These marked trees receive special fertilizing and pruning treatment each 
year until they either recover or are pulled out as hopeless. This simple 
method of keeping track of each tree has cost less than $10.00 per year for 
a 40-acre orchard. An accurate tree to tree estimate of the crop is needed 
anyhow, and it takes but a second to make the additional note on the 
condition of each tree. 
As to Unprofitable* Varieties. 
In order to make the subject more concrete, some of the practical re- 
sults of the four years’ record in this particular orchard are given. The 
relative productiveness of and profit from thq several varieties has been 
brought out quite clearly. The average annual yield per healthy tree has 
been as follows: 
Grimes 3 y 2 bbls. 
Ben Davis 2% “ 
York Imperial 2y 2 “ 
Wine Sap l y 2 
Albemarle Pippin % “ 
Pilot y 2 “ 
The Yellow Newtown and Pilot have not been profitable. This soil, 
a Hagerstown Stony Loam, Tather deficient in humus, is not adapted to the
