$2,285.89. The following itemized account of the 1912 opera- 
tions shows an interesting relation between labor and materials 
in doing work of this kind. The abnormally high cost of weed- 
ing is undoubtedly attributable to the large amount of horse 
manure used during 1911.

The high cost of raking and preparing soil is due to a 
protracted drought at the time, making the ground hard and 
lumpy, and consequently very difficult to pulverize. The total 
estimated cost of getting a permanent lawn by the top-soil 
method was about $40,100. The total saving to the Garden by 
folowing the methods adopted here has been (%40,100— 
$2,285.89) $37,814.11. 
Besides the work outlined above, our laboring force has 
carried on numerous other operations, such as mowing of lawns, 
hauling and stacking top-soil and manure, cleaning and weeding 
paths and steps, painting, and whatever other general work has 
come up. In addition to this they have dug about 450 holes 
varying from 3 to 8 feet in diameter and 3 feet deep, for the 
gardeners. These were filled with a mixture of leaf-mould, 
manure, and rich soil in varying proportions, depending on what 
was to be planted in them. 
To the gardening force there has been transferred one man 
from the laboring force for 229 working days. Counting the 
number of days in which the gardening force was working, this 
means that the laboring force loaned the gardening force one 
man each day, on an average.
