of from two-thirds to three-fourths of the entire cost, so far 

 as regards the walls. 



As no mere statement of this kind will enable any one to 

 judge fully of the character of the work, or to gain much 

 information of the detail of its construction, 1 would invite 

 the Committee, and all others interested, to visit and examine 

 the buildings at any time when it may meet their collective 

 or individual convenif^nce. The location is a mile and a half 

 northerly from the village in Fitchburg. 



Statement of Joseph Upton, Jr. 

 Wishing last spring to try an experiment to test the value 

 of guano compared with compost manure from my barn 

 cellar, I manured one acre of land in the following manner : 

 On two-thirds of the acre I spread 20 common ox cart loads 

 of compost manure from my barn cellar, and plowed it in. 

 On the other one-third, I sowed 200 lbs. of guano, broadcast, 

 and harrowed it in ; 1 then planted the whole acre with corn, 

 putting a small handful of plaster and ashes into each hill, 

 and cultivating the whole alike. On the 10th day of October 

 the Committee on grain examined that acre, and, in their 

 judgment, there was but very little difference in the corn on 

 the two parts. They selected one square rod, the ears on 

 ■which weighed 50 1-2 lbs. ; and they gave me the second 

 premium. As near as I can calculate the expense per acre 

 manured as the above two-thirds was, would be about $40,00, 

 and the cost per acre manured as the one-third was, with 

 guano, about $25,00, showing a difference of $15,00 per acre 

 in the expense in favor of the guano.
