EXPERIMENTAL STATIOXS — REPORT FOR 1881. 329 



The extent of the plots was half an acre each, and the soluble 

 and insoluble phosphates were applied on alternate ridges in the 

 middle of a turnip field whose soil was fairly uniform. No 

 comment is required upon these figures ; they speak for them- 

 selves. The season was a very unfavourable one. The produce 

 with dissolved phosphates was half a crop, while that with un- 

 dissolved phosphates was an utter failure. These experiments 

 have settled the question as to the kind of phosphates required at 

 Yester, but it is the intention of the Marquis of Tweeddale to 

 perform another experiment on these plots with the succeeding 

 crop, in order to see what is the unexhausted v^alue of the 

 manures upon them. 



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 —
