a few that had evidently been induced to germinate by the excess 
of moisture. The power of the male elements to withstand long 
continued moisture was apparently great, for at the close of the 
experiment, after the rain had ceased, many authers opened and 
shed an abundance of pollen, while the anthers of flowers on 
adjacent trees had withered and fallen several days previously. 
After turning off the water on the twenty-fifth, an examination 
with a hand lens was made of flowers on both the side nearest to 
and that farthest from the spray, with the following result: 
Of 403 flowers counted on the side receiving the most water, 
103 were possessed of plump anthers and apparently normal 
stigmas. 
Of 303 flowers upon the dryer side, only three were still fresh 
and capable of fertilization. 
The effect of the water in retarding the development of the 
flowers was strikingly illustrated. 
Effect on foliage —A second effect and one not looked for 
particularly, was the disastrous effect of the rain upon the foliage 
of the tree. After the spray had been applied three or four days, 
‘the foliage which, up to that time had appeared ‘perfectly normal, 
assumed gradually a sickly color and became spotted with small 
irregular grey spots, surrounded by red borders. The petals of 
the flowers tuo were affected in a similar way, the spots often 
assuming a bright rose color. A microscopic examination 
revealed the presence of no fungus, although the symptoms indi- 
cated the attacks of the leaf-blight (Antumosporium maculatum, 
_ Ley.). While this peculiar spotting was not entirely absent from 
the untreated tree, upon this it was observable only in small 
amount. This peculiar sickly foliage has not recovered its green 
color and at the present writing (September 22) the differ- 
3 - ence is easily observable from a distance of one hundred yards. The 
¢ small size of the individual leaves and their reddish coloration 
__ mark the tree as decidedly diseased. 
Although, as mentioned above, after the spray had been removed 
many flowers with perfect anthers and pistils remained capable
