1891.] PUBLIC DOCUMENT — No. 4. 17 



I will pass on to a consideration of what they have accom- 

 plished, and when I say this I wish you to bear in mind that 

 I do not profess to be able to measure, nor do I believe 

 any man can, their full value or their full usefulness. 

 In 1889 tnere were printed and sent out by the various 

 experiment stations in the United States 280 bulletins and 

 reports, including 10,000 pages of printed matter. I have 

 no means of knowing, and have seen no figures showing the 

 mailing lists of the various stations, I can simply give the 

 fact in regard to our own State. We have in New Hamp- 

 shire a mailing list of 7,000 farmers who receive every 

 bulletin and report that is sent out. Then there are other 

 ways which we have of getting the results of our work before 

 the farmeis of the State, through farmers' institutes, agricult- 

 ural papers, etc. 



From among these bulletins I have selected a few for the 

 purpose of showing just where they have been of practical 

 value. I have here a bulletin from Cornell University, 

 Bulletin No. 13, in which the subject of manures is treated, 

 the results of Avhich you have seen in the agricultural papers, 

 because this bulletin has been very widely copied. Let us 

 look for a moment at the loss which results from careless 

 methods of handling barnyard manures. Professor Roberts, 

 the director of the station, says that their experiment, which 

 was conducted by taking certain portions of horse manure 

 from the yard and analyzing it, and then exposing it to the 

 effect of rain, showed that there was a loss from a ton of 

 manure by leaching of $1.03, which represents 42 per cent 

 of the entire value. Now, this represents a loss of over 

 $6.00 per year on each and every horse where the manure is 

 left exposed and unprotected. We have in the United States 

 13,173,000 horses. Professor Roberts says that, from his 

 experience in the State of New York, a large majority of the 

 farmers leave their manure out in this way unprotected. But 

 let us suppose that only one-third of it is left exposed ; we 

 there have a loss which might have been prevented, and 

 which amounts to nearly $26,000,000. If Bulletin No. 13 of 

 the Cornell University Experiment Station could be properly 

 appreciated, much of this would be saved. I have no doubt 

 that one-third of the value of all the horse manure in the 

 country is sacrificed in this way. In the same bulletin the
