did it an injury. Even at that the blight is seemingly not very virulent 

 and the stock below the injured area is healthy. Whether it will come 

 out again in the spring is problematical. 



No. 106 — Sept. 8^ '26. Reported tree looking splendidly, with 

 blighted area well closed in. 



May 4, '27 — Injected antigen (5th dose). Tree looks fine. 



May 25^ '27. Noticed tree doing badly. Old area of callus necrotic. 

 Injected antigen (6th dose). 



May 31, '27. Injected spl antigen in two places. Former antigen 

 ineffective. Bark and cambium necrotic almost around the tree. Only 

 a little strip of live cambium (about one half inch) yet holding. It 

 looks as though I am going to lose this tree. 



June 15, '27. Tree looks better. Another spl antigen. 



June 27, '27. Decidedly better. Injected another spl antigen. 



July 11, '27. Very much better. Injected another spl antigen. 



July 15, '27. Injected another spl antigen and still another in 

 central limb. This limb looks as though it were going to be surrounded 

 and die and this second injection is in the hope of saving it. 



Sept. 2, '27. Many limbs and areas blighted, central limb above 

 referred to is dying, but otherwise the tree is in good shape, bearing a 

 quantity of burs. The strip of new callus at the root is now two inches 

 wide, although there is quite a denuded area yet to cover. 



No. 112 — This is a plant of Morris No. 1 which was reported last 

 year, you will recall, as having been blighted all way around the trunk, 

 the callus jumping the gap, and on Sept. 8, '26, was in good shape. 

 This tree had only one dose — not considered enough to protect, much 

 less to cure. 



May 4, '27. Right limb blighted. Second antigen injected. 



May 30, '27. Antigen injected. Area of necrosis started in the 

 old scar of last injection and is involving the old callus, half way 

 around the tree. Plant looks badly. 



June 15, '27. Looks so badly I believe it will die. My last antigen 

 played havoc. North limb dead and it appears useless to give another 

 injection. 



June 18, '27. Still hanging on. Cut off north limb and gave a dose 

 of antigen No. 2. 



June 27, '27. Plant much better. Apparently recovering. 



Sept. 2, '27. Tree looks nicely. Has a fine growth. Scar healing 

 over beautifully, although not nearly covered as yet. Apparently this
