Certain observations relative to the incidence of this disease 
are of interest here. In survey trips made by the writer in 1915 
anthracnose was found in only 1 among 23 cucumber fields visited 
near Wautoma, Wild Rose, and Almond, Wis., in none of the 10 
fields visited near Portage, and in only 1 of the 13 fields visited at 
Baraboo. On the other hand the disease was found in 3 among 
the 10 fields visited at Neshkoro, 2 out of 6 at Princeton, and 17 out 
of 21 near Sparta. Thus the disease seemed to prevail in certain 
localities and not in others. 
In rather extensive surveys made in the region around Ripon, 
Wis., in 1914 and again in 1916, Mr. Carsner was unable to find this 
disease although it was abundant around Princeton, 16 miles dis- 
tant. 
In 1916 the writer was unable to find this disease in 12 cucumber 
fields visited near Baraboo, but found it in 9 out of 11 fields near 
Princeton. With regard to these two localities, the situation re- 
mained much as in 1915. 
In the neighborhood of Madison, anthracnose was found in 1916 
in only 1 out of 39 garden patches of cucumbers and in none of the 
8 private fields of muskmelons. In 7 gardens visited at Burnett, 
Wis., no anthracnose was found on cucumbers. 
In the southern melon region in 1917 the disease was found quite 
prevalent among watermelons, but in 16 fields of muskmelons visited 
near Blackville, S. C., anthracnose was found in only one field, and 
in that case it had very evidently come from a row of badly dis-
