lot of callus is being thrown out but the healing process is not con- 

 clusively in evidence yet. 



July 27. Blight area ceased invasion entirely on limbs. Bark has 

 separated and fallen off and infections are almost healed over. 

 These are the limb infections above referred to. Received second in- 

 jection on this date. 



September 10th. Small blighted areas on limbs healed entirely and 

 the larger area in the crotch has come together considerably al- 

 though not so noticeable on account of its size. 



October 26th. All small areas are fully healed and look healthy. The 

 large area is about half covered with healthy looking callus and 

 from all appearance blight is fully under control. This is the only 

 Japanese chestnut that has even recovered for me although I made 

 special effort to save them, cutting out the blighted areas and cover- 

 ing with antiseptic and paint or wax. 



July 18, 1926. Tree looks fine and covered with burs. Blighted area 

 in crotch about an inch wide yet and healing nicely. Another in- 

 jection given on this date. 



August 19th, 1926. Injected north limb. 



September 8, 1926. Tree looks splendid. 



One more. Very interesting. Quoted fully. 

 No. 112 



August 4, 1925, Tree 30 inches high and 1-2 inch in diameter. 

 Morris No. 1 grafted in 1921' on a native American stock. Morris 

 No. 2 is a native American x chinquapin hybrid, I believe. Tree is 

 badly blighted at crown. Perhaps too badly to do anything with. 

 I-arge injection of serum given on this date. 



August 10th. Noticed that the bark is dead all the way around the 

 plant and the bark separating exposes the wood under the cambium. 

 A circle three eights of an inch wide all around with much greater 

 width on one side, about 1-2 inch. Had I known this on August 

 4th, I should have saved my serum. 



August ].5tli. Blight seemed checked and callus is being thrown out 

 from above in large amounts. Covered the denuded ring with 

 paraffin. It is now dawning on me that perhaps the callus might 

 jump the gap and take up the circulation again. Tree is sending 

 up shoots from tlie roots, which is one of the best evidences that the
