The percentages of wilted Norton plants reported for Georgia in 
1917 by Mr. J. A. McClintock are summarized in Table 5. As not 
all of these fields were visited, it is quite likely that some of the 
injury attributed to wilt may have been due to blight or root-knot.

The percentages in Table 5, which probably refer to apparent 
resistance, agree fairly well with those in Table 4. In some in- 
stances, as in Glynn County, it is quite possible that wilt was not 
always distinguished from blight or root-knot. For Chatham 
County only one result is reported, and it is a percentage which is 
very likely much higher than the average for the 35 tests. But even 
as the results of these tests are reported, they show that the Norton 
is much more resistant to wilt than the commercial varieties planted 
beside it. 
The results reported by Edgerton for Louisiana in 1920 are sum- 
marized in Table 6. They include data on Edgerton's wilt-resistant 
varieties, Louisiana Red and Louisiana Pink, and also on several 
commercial varieties. The percentages are arranged in two columns :
