NOTES OX UROMYCES AMYODALI COOKE, 
It is highly probable that the disease has been with us for 
some time and gradually gaining ground before attracting atten- 
tion to its cause, for I have even known its effects to be con- 
founded with the tints of autumn, and this seemed all the more 
plausible as it is usually associated with the shedding of the 
leaves. 
Time of Occurrence. 
The time of appearance varies in different seasons, and the 
later it is the less damage it does. It also varies in its virulence 
according to the nature of the season. Thus in the Royal Horti- 
cultural Gardens the attack was very mild in 1888-89, then very 
bad in 1889-90, not very bad in 1890-91, and speaking for the 
Colony generally the past season was favourable to its spread. A 
grower in the Goulburn Yalley writes : — "This season (1894-95) 
owing no doubt to the continued rains of the spring and the very 
heavy downpour in January, the attacks of this fungus have been 
very serious, causing a very large proportion of the leaves of the 
peaches to fall prematurely. Many acres of trees were thus laid 
bare for about 18 inches from the crown, only the younger wood 
surviving, and as a consequence nearly all the fruit for the coming 
season must come from near the top. Plums and prunes suffered 
severely, many trees being completely denuded of foliage by 
March." Thus, the disease seems to be intermittent in its 
character according to the prevailing weather. The following 
table shows the rainfall for the critical months : —
