All of these 58 varieties being subjected to eight different series, 

 made a total of 464 experiments. 



The effect on the germinating power of all the grains and vetches 

 was very similar, so small in fact as to be almost negligible. No 

 decided varietal difference was noted on any of the seeds tested or in 

 the quality of the nuts. The almonds showed a slight impairment of 

 flavor when exposed to high temperatures or for long periods to the 

 action of either carbon disulphid or cyanide. A short exposure to 

 either of these chemicals, even at a strong concentration or an eight 

 hour exposure to a temperature of 125° F. all left them in apparently 

 a normal condition. 



The most striking variation was seen in beans, hence the report is 

 shown in full for only this one group and for only seven of the eight 

 series. The eighth series was at a similar temperature to number one, 

 but for a shorter time, the results of the two being so alike as not to be 

 worth repeating. This table then is a summary of seventy-seven 

 experiments in which is seen a range in germination from 22 per cent 

 to 100 per cent, and yet the average for the whole group is only 5 per 

 cent less than that of the check, and small as was this loss in the beans, 

 the variation for the grains was even less. 



Beans are commonly reported to be especially liable to injury from 

 fumigation, yet when the excessive dosages or temperatures that were 

 used are considered it is seen that in most instances no injury whatever 

 occurred and even these discrepancies may be and probably are, partly 

 due to improper germinating conditions, for the greater variations come 

 in temperature tests and are not in proportion to the degree of heat 

 used. Every effort was made to have optimum germinating condi- 

 tions, the work being done in a fairlj'- constant temperature and all 

 tests discarded that seemed to fail in any way. 



Considering the table as a whole it would seem that beans are not so 

 susceptible to this form of injury as is usually thought, providing the 

 work has been carefully done and on cured stocks, these experiments 

 being on dry beans. Isolated instances may be selected from the table 

 which would give the impression that these treatments are dangerous. 

 Just as occasionally we have reports of fumigation injury, but as a
