entry, so that potatoes and other bulky articles may be brought in and re- 

 moved without contaminating the laboratory unnecessarily. A block and 

 tackle fixed over the stairway is used for lifting and lowering heavy articles. 

 Light is provided below by four windows, and the cellar is artificially 

 illuminated by means of two electric drop lights over the sorting bench. 



In the fall of the year the space available is only just sufficient for the 

 crops to be graded and stored. Thus to take the potato experiments alone 

 which were controlled and carried out by the laboratory, there was in- 

 volved the handling of 12,840 lbs. of potatoes, made up of over 3,000 

 separate lots. When it is borne in mind that this meant the careful indi- 

 vidual examination of every tuber, of which there would be perhaps 36,000, 

 not once only but several times in the majority of cases, it becomes clear 

 what an amount of careful work is called for.
