(1) Blight-proof stocks with grafts each of four Pit-liable varieties. Of the original stocks 

 used French Paradise and Duchess of Oldenburg died during the past season. 



Northern Spy bore no fruit, and the four healthy grafts were also barren. 



Of the remaining three stocks the results are shown in the following table :

SUMMARY FOR THREE YEARS. 



The scions were Cleopatra, Annie Elizabeth, Cox's Orange Pippin, and Bismarck, and were 

 grafted on 5th September, 1911. They are all very liable to Pit in the Burnley Gardens, although 

 Cox's Orange Pippin was the least liable. They did not produce fruit on all the stocks, but the results, 

 where fruit was produced, are shown in the following table :

 one on which the fruit was always pitted was Northern Spy.
