after very closely. I would not urge late cultivation under 

 other conditions at all. I have had considerable experience in 

 this matter and I think the plan outlined is a good one. 



Mr. Johnson: I have traveled some in South Dakota and 

 made some observations that I think are right in line with this 

 matter. I heard the statement made that it was impossible to 

 raise trees there on account of its being so dry, and I went 

 there partially to see about it. I have seen trees that it was 

 almost impossible to make grow, because they were almost 

 smothered in quack grass. In many cases I would not have 

 taken the plantation and resurrected it from the dead, if it was 

 given to me. I would rather take a piece of land near it and 

 commence new. I think this state of affairs was partially due 

 to the fact that the land was put out to trees too soon after be- 

 ing broken up. When this is the case it is very liable to go 

 back to grass if neglected. 



Dr. Wentworth: I have had quite a little experience in grow- 

 ing forest trees, and I have had to contend with all the diffi- 

 culties which have been mentioned. I have succeeded in get- 

 ting away with the weeds and at the same time avoided the 

 evil of very late cultivation. I would recommend this plan: 

 Continue your ordinary cultivation until perhaps the middle of 

 July, and then change to surface cultivation, just cutting the 

 the weeds and not developing the trees at all. This can be 

 done.
