Remarks. 



These trees iNos. 43-50) were 

 all in about the same condi- 

 tion. They stood in a row 

 near together and had re- 

 ceived good culture. They 

 were rather old dwarfs 

 which had been severely 

 pruned back some five or 

 six years before, so their 

 entire tops were of vigorous 

 young growth. Bloomed 

 nioderatel.y, but fruited well.
