also evident that the creosote, though unable entirely to control the 
mold, seemed to prevent the development of sap-stain. From the 
evidence it would also appear that heating the creosote to 150° or 155° 
F. does not increase its effectiveness to any marked degree, the differ- 
ence in the percentage of moldy spokes in the two treatments being 
less than 1 per cent. 
METHOD OF LOADING CAR > T 0. 2. 
The second car, containing 1,032 salted, 1.013 borax-treated, 300 
lime-treated red-oak. and the remainder untreated, white-oak escort 
spokes, was loaded 
on August 3 and 5. 
Those spokes that 
had been salted were 
exceedingly moist, 
owing to the hygro- 
scopic property of 
the salt. On many 
of these species of 
Penicillium were 
found. The limed 
spokes were dark in 
color and in a few 
cases seemed to be 
developing sap- stain. 
The borax-treated 
spokes were appar- 
ently quite free from 
fungi. 
The method used 
for stacking the 
spokes in the second 
car differed somewhat 
from that in the first. The base of each rick was constructed in 
the same manner, though of four instead of six layers. Upon this 
base the spokes were carefully stacked, using two H-inch by J -inch 
crossers of elm between successive layers (fig. 19). Each rick held 
on an average 840 spokes. The doorways were closed in the same 
manner as in car No. 1. This consignment left the yard on August 
6 and arrived at the same factory located in the North on August 20, 
a period of two weeks in transit, During this time the weather was 
hot and comparatively dry. 
CONDITION OF SPOKES IN CAR NO. 2 UPON ARRIVAL AT DESTINATION. 
On August 21 the spokes were unloaded and inspected by C. J. 
Humphrey and the writer. Table II gives the location of the dif- 
ferent lots and their condition upon arrival.
