rust. The peach rust, in the south, takes the place of the 

 peach yellows. Fortunately for the southern peach -grower, the 

 rust has never shown a tendency to spread and wipe out the 

 peach orchards in the manner that the yellows has in the north. 

 It is almost a curiosity in the great commercial peach orchards of 

 Georgia. We have to hunt for it before we can find a satisfac- 

 tory subject to photograph. It is more apt to be found in some 

 tree along the roadside, but it does in one single season what 

 the yellows take two or three, or even five years to do. It kills 

 the tree at once. 



The peach is also affected by another curious disease called 

 the 'little peach.' It is a disease which, up to the present time, 

 is very little known outside of the state of Michigan, but there, 

 in a few localities, it has shown a very destructive tendency. I 

 will go over with it so that you may get acquainted with it ; so 

 that if it should appear here you may recognize it. The most 

 striking feature of the disease is the small size of the fruit. A 

 tree in a well -cultivated and a well-cared-for orchard may be 

 noticed to have fruit that is from one- to two-thirds normal size, 

 and as the fruit comes on it is belated in ripening all the way 

 from a day or two to a week. In some cases it is a month 

 behind time. The fruit of such a tree is not a healthy fruit. 

 The fruit is small in size, and entirely abnormal in that respect 

 when compared to a healthy peach from an unaffected tree. 

 The foliage is small, as well as the fruit. This disease has had a 

 very destructive effect upon the orchards in the state of Michi- 

 gan. At present it seems to be confined to a certain diseased 

 area. It appeared two years or more ago, and the next year 

 had spread to larger trees, as you see by the photograph. The 

 season these photographs were taken it had spread still further 

 through the tops. This picture shows another orchard in 

 Michigan in which the ' little peach ' is at work. By casual 

 observation you can see on the branches the character and 

 growth of the disease. 



Now I want to give you a little idea of the way we went at 

 this disease for investigation purposes. Of course, in this state, 

 it being an entirely unknown disease, we made up our minds 

 that we must study the disease from the tips of the leaves to the 

 end of the roots; study it from one end to the other. This
