EXPERIMENTAL STATIONS — EEPOET FOR 1880. 



Scotland without a small branch experimental station, or a soil 

 of any breadth that was not being made to tell what Vv^ere its 

 chief wants. The former need not cost more than from £50 to 

 £100 a year, and a small five-plot test or similar inquiry need 

 cost nothing at all ; but the saving which w^ould result from their 

 institution would amount to many thousands annually. 



Scheme of Experiments at the Experimental Agricultural 

 Stations of the Highland and Agricultural Society 

 OF Scotland, commenced May 1878. 



At each station there are 10 acres under experiment, divided 

 into 40 plots of 1 rood each. The cropping is a rotation of 

 turnips, barley, grass, and oats. The chief object of the experi- 

 ments is to determine the crop-producing value of the various 

 forms of the most important manures. The manures on each 

 plot contain 20 lbs. j)bosphoric acid, 15 lbs. potash, 5 lbs. 

 nitroo'en.
