BULLETIN 1037, U. S. DEPARTMENT OF AGRICULTURE, 



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. 



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 arrival.
