Sometimes the loading had proceeded so far that it was impossible to satis- 

 factorily judge the contents of the car. 



It occurred to Dr. Marlatt to place the responsibility of the powdery scab 

 elimination upon the shipper, so, on April 16, the amendment here presented 

 for the State regulations followed a similar order issued by the Federal Hor- 

 ticultural Board:
