Conclusioii. 



Very little satisfactory iuformatiou has beeu obtaiued by the above 

 experimeuts, but the following facts are as fully demonstrated as is 

 possible by one series of experimeuts. 

 1st. That turpentine and benzine will destroy peach trees when 



applied to branches or trunk. 

 2d. That the fruit buds are not protected by the ordinary light 



covering of mats, pine boughs, etc. 

 3d. That the glue solution as applied is of no value in protecting 

 the buds. 

 The system of covering trees b}' binding over must be more fully 

 worked out as to detail, to demonstrate its practicability and economy. 

 Further experiments are required to demonstrate the value of lin- 

 seed oil and shellac. 



GIRDLING APPLE TREES TO PRODUCE FRUITFULNESS. 



In many sections where the soil is moist and rich, fruit trees grow 

 largely to wood and foliage, and fail to produce fruit until they reach 

 considerable age and size. 



To discover some means of hastening the fruiting of such trees 

 the following experiments have been made. 



A row of crab apple trees of about the same size and condition of 

 growth were selected and treated as follows. 



EXPERIMENT NO 1. 



1st. Three trees were girdled by cutting out a ring of bark 1-8, 1-4 

 and 1-2 inch wide at the ground, July 12th, 21st and 29th. 



2d. Three trees were girdled just below the main branches with the 

 three widths of girdle as in 1st, July 12th, 21st and 2yth. 



3d. The same as above was made on one or more main branches 

 with the three widths of girdle, July 12th, 21st and29th. 



Besult. 

 1st. All the girdles made near the ground healed over readily and 



completely. 

 2d. Those on the main trunk healed less completely, but sufficiently 



to ensure a good growth of tree and the covering of the injured 



part in another year. 

 3d. The girdles made in the branches healed less completely than 



the last, and in two instances the new growth failed to meet and
