JIETHOD OF LOADING CAR NO. 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 Ij-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 Fig. 19.—" Ricking," or stacking, treated escort spokes in a box car (car No. 2)..
