270 ~=Reporr oF THE HorricuLruRAL DEPARTMENT OF THE 
pheric conditions that have a tendency to increase transpiration, 
results in an increased thickness of cuticle.” 
In the spring of 1905,.preceding the unusually severe bor- 
deaux injury of that year, the weather was such that foliage was 
tender and succulent. The shoots came out under abnormal 
conditions; the weather was warm, foggy and wet. The new 
growths were what ‘the fruit grower calls “sappy.” It can 
well be assumed that the protective cuticle was poorly formed | 
and the parts under it spongy and weak. The power to resist 
entrance of solutions must be low in foliage such as was pro- 
duced under these conditions, and the injury of this year well 
illustrates the relations of weather to succulency of foliage and 
consequent injury. 
Table V is a record of the moisture and temperature and 
meteorological conditions attending the experiments under 
discussion.
