COLLECTION OF SEED.

The undesirability of storing seed in oiled cloth bags is very plainly 

 brought out by the table. The low percentage of germination of seed 

 so stored is probably due to the absorption of oil by the seed coats. 



In attempting to determine the effect upon germination of the 

 different temperatures under which the seed was stored, the germina- 

 tion percentage of those stored in the oiled bags was not considered, 

 since its low figure was manifestly due to the container and not to 

 the temperature. With the figures for the oiled bags eliminated, the 

 following were the average percentages of germination under the 

 different temperatures : Fluctuating, 55.5 ; indoor, 52.7 ; low, 46. 



Seed stored in bottles showed, under the different temperatures, 

 the following average percentages of germination : Fluctuating, 60.2 ; 

 indoor, 60.6 ; low, 62.3. 



It will be seen that the greatest difference in the percentage of 

 germination under the three temperatures is only 2.1 per cent, and 

 this might easily be due to a slight variation in the quality of the 

 seed. It would seem, therefore, that differences in temperature have 

 little or no effect upon seed stored in sealed glass bottles for one year. 

 Another experiment discussed later tends to prove that the best tem- 

 perature for storing seed is one ranging a little above F. The 

 object of storing seed in so many different places was to determine 

 whether geographical situation has any effect upon germination. 

 Table 8 seems to indicate that some locations should be given 

 preference.

The relatively high germination of seed stored at high altitudes, 

 such as at Fort Bayard, Pikes Peak, and Pocatello, all in the Far 

 West, is in striking contrast to that of seed stored at low altitudes in 

 the Middle West, at Lawrence, Kans. ; Warsaw, Ky. ; and Dundee, 111. 

 The seed stored at Lake Clear Junction, N. Y., showed a relatively 

 high percentage of germination, while that stored at the remaining 

 points germinated moderately well. If conclusions can be drawn
