a great many factors coming up that might influence that 

 point. But I think that that statement holds good, that the 

 earlier bearing the tree, the shorter lived it is. I can't bring 

 any evidence to bear on that point aside from observation. 



MR. FRASER. I would like to ask further, is there 

 not a normal fall growth in your young apple trees, up to 

 ten years? I mean, the growth after August? 



PROFESSOR JARVIS. Not a normal growth. Some- 

 times we have a little cultivation where we will get a second- 

 ary growth, but I have never noticed any on the trees except 

 where we have had abnormal fertilizing or cultivation. 



MR. FRASER. We in western New York expect a 

 growth in the fall after August. On young trees from three 

 to ten we expect some growth, and that is one reason why I 

 have had difficulty in determining when summer pruning 

 should take place, because there is that normal fall growth. 



PROFESSOR JARVIS. I would like to inquire if any- 

 one here has noticed any amount of fall growth in our New 

 England orchards. Personally I haven't noticed any to 

 speak of, and wherever I have noticed it I have always been 

 able to find a reason for it. 



MR. BOWEN OF LAKEVILLE. I have got some trees 

 from New York and they always give me six or seven inches 

 of growth after the first of August. 



PRESIDENT FROST. Is there anyone else in the audi- 

 ence who may have made any observations on that? 



MR. R. H. RACE OF EGREMONT. Mr. President, I 

 have practiced some summer pruning and have always found 

 it dangerous because it induced a fall growth. The fall 

 growth, way up to September, is dangerous to a young tree, 

 because of the severe winters we have and the starting of 

 the growth in the fall is injurious because they can't stand 

 the hard winters. Take raspberries : I started to prune my 

 raspberries and blackberries in the summer as somebody 

 said, ''You don't want your raspberries to grow four and a 

 half feet tall. Pinch them off." Oh, no! That produces a 

 late growth that doesn't harden and they winter-kill right
