Honor dble Commissioner of Agriculture^ Albany : 



Sir: This bulletin is submitted for publication under the 

 Experiment Station Extension Law (Chapter 437, Laws of 1896), 

 which appropriates funds, " for the purpose of horticultural ex- 

 periments, investigations, instruction and information, in the 

 fifth judicial department " of the state, and for " disseminating 

 horticultural knowledge by means of lectures or otherwise." 

 The papers herein contained are incidents to our main lines of re- 

 search, but they seem to be worth permanent record. The in- 

 formation contained in the first article is much called for by the 

 fruit-growers of our district and the apparently increasing preva- 

 lence of root-galls on fruit trees is a subject of much apprehen- 

 sion. It is hoped that the remarks upon the treatment of win- 

 ter-injured trees may be timely.
