Peaches, and the Treatment of Injured Fruit Trees. — Not 

 only the fruit buds of peaches were killed, but the trees them- 

 selves were very seriously injured upon the University place. 

 Most of the last year's growth was wholly killed, and in many 

 instances vigorous branches an inch in diameter were destroyed. 

 All peach wood was markedly browned and discolored. 



The proper treatment for any trees so seriously injured as this^ 

 is to cut them back very heavily. This severe heading-in — some- 

 times to the extent of three or four feet — removes the driest and 

 weakest portions and concentrates the energy of the tree into a 

 comparatively small area of top. Heavy pruning always tends^ 

 towards the production of wood, and this wood production is 

 probably never more needed than in winter-injured trees, for it 

 tends to renew the vitality of the tree. The philosophy of this 

 becomes apparent upon a moment's reflection. The browned and 

 injured wood can never regain its former usefulness. New tissue 

 must be developed as quickly as possible in order tO' carry for- 

 ward and to maintain the vegetative energies. This new tissue is 

 laid on over the old, and the old, thereby, quickly becomes sealed 

 in, so to speak, and removed from the agencies of decay. Every 

 observant fruit-grower know^s that if a tree which is severely 

 winter-injured in limb and trunk were to bear even a partial crop 

 of fruit in the coming season, it would very likely die outright. 

 If, however, all its energies were directed to the development of
