trellises or untrimmed. No advantage was gained either in 
early ripening or quality of fruit. Apparently the only advan- 
tage of this system is that plants can be set much more closely 
together without crowding. In any case the work of pruning 
and tying the plants to stakes would make this system too 
expensive for anything but a small garden. 
Bulletin No. 30 of this Station gives the results of some work 
done during the summer of 1902 0n spraying cucumbers and 
inelons to prevent melon blight. This experiment was repeated 
during the years 1904 and 1905. 
June 10, 1904, a plot consisting of four equal rows of long 
green cucumbers was planted: Applications of Bordeaux were 
given on June 18, July 2, .13, 25, 30, August 6, and Io. 
Table 18 gives the dates of picking and the number of 
cucumbers from sprayed and unsprayed plots.

All cucurbits were particularly productive in 1904, and no 
disease developed in them. From the first spraying a difference 
could be seen in favor of the unsprayed plants. The Bordeaux 
caused a thickening of the tissue of the leaves and retarded the 
growth of the plants, though it did not kill any of the leaves. 
This deleterious effect of Bordeaux spraying was not noticed 
in the work of the previous year, but was very noticeable on 
all cucurbits during 1904 and to some extent in 1905. ‘The 
work along this line in 1905 gave similar results to that of 1903.
