MAILING LIST. 



During the year the mailing list was increased by about 1200. 

 It now numbers 3000 names, (not including the official list, ) of 

 which 2200 are in Arizona and the rest in other States and coun-

 60,000, it appears that our publications reach about 3.7 per cent 

 of those actively interested in them, this being a larger proportion 

 than is reached in most of the more populous States. The very 

 fact, therefore, of a sparse population enables the Arizona Station 

 to reach a larger proportion of its public and should lead to a 

 quicker general utilization of its results.

The series of "Timely Hints for Farmers" is anew departure 

 for the year and marks a special effort on the part of the Station 

 staff to reach the farmers of the Territory with needed information 

 on living questions, presented at the time and in the manner most 

 likely to be useful. These "Hints" have been sent not only to
