The amount of rot is not great except perhaps in Telegraph and Bel- 

 mont, and it is probably not chargeable to the pecaliarities of the given 

 varieties, except in the instance of the Yellow Plum. In Table XXII, 

 above, all the entries are Ignotum, and it will be seen that the figures run 

 from 3.7 to 16.6 per cent. t^a;!? 



Altogether, therefore, we are able to draw no definite conclusions from 

 this year's studies of fruit-rot, largely, perhaps, because the disease was 

 not sufficiently severe to emphasize itself in particular treatments. 



17. Souther?! or field blight. — The accompanying 

 illustration shows a trouble which was serious upon 

 some of our tomatoes this year. The leaves become 

 dull or slightly yellowish and curled, as if suffering 

 from drouth, and the ends or individuaj 

 leaflets shrivel and droop and finally 

 become dry and black. The upper- 

 most leaf in the engraving shows the 

 shrivelled, dead and spindling extremity 

 in a characteristic manner; and the low- 

 est leaf shows the injured portion 

 in an early stage of the disease. 

 The middle leaf has not reached its 

 normal size, and looks as if it were 

 suffering from lack of water. This 

 trouble is probably the disease 

 described as the Southern blight by 

 Professor B. D. Halsted, in Bulletin 

 19, of the Mississippi experiment 

 station. Specimens were submitted 

 to Professor Halsted, 

 who thinks that the 

 disease is probably 

 identical with the 

 southern one. This 

 is not the first record

of the occurrence of the disease in the 

 north. In a recent issue of Garden and 

 Forest, Professor Halsted reports it from 

 Syracuse, N. Y., where it had invaded 

 three tomato fields. Apparently the same 

 disease has been reported to me from 

 three localities in this state during the last two seasons, and in two cases
