Result . 

 All the trees except those treated with ghie, linseed oil luid tur- 

 peutine were killed. The trees treated with linseed oil and turpen- 

 tine were badly injured, but are now making a good growth. The 

 tree treated with glue was wholly uninjured, but showed no more 

 fruit buds than those unprotected. 



EXPERIMENT NO. 3. 



To still further extend the last experiment, a single tree which 

 had a large number of fruit buds upon it was selected. Three 

 branches of as nearly the same condition as possible were selected, 

 and treated with each of the following materials applied with a brush. 



1st. Linseed oil. 



•id. Linseed oil and turpentine. 



3d. Linseed oil and benzine. 



4th. Benzine and rosin. 



5th. Shellac. 



6th. Glue. 



Result. 

 Upon examination in March it was found that the buds covered 

 with linseed oil, shellac and glue were apparently uninjured, but as 

 the season advanced it was found that the turpentine and benzine 

 had been applied to branches near the trunk and had spread over it 

 so much as to kill it, consequently those buds which seemed unin- 

 jured failed to start. 



EXPEPaMENT NO. 4. 



Four trees of the same kind were selected and covered with straw 

 matting. After the mat was bound about the tree, dry sawdust was 

 poured in at the top of one, moist sawdust into another, and coal 

 ashes into another, and the fourth contained nothing. After tying 

 up the ends of the mats, the whole was supported by two strong 

 stakes. 



Result. 



The trees covered and protected with dry sawdust show more 

 uninjured fruit buds than those covered in other ways or unpro- 

 tected. 



The trees protected with wet sawdust and ashes showed no more 

 uninjured fruit buds than the same kinds unprotected. 



This experiment was carried out in detail by Mr. L. F. Kinney of tlie Class of '88.
