114 ON EESULTS OF EXPERIMENTS WITH 



is, that to take an average of five years in wliicli I tried a plot 

 without manure, that it did not grow crop sufficient to pay 

 labour, seed, and rent. On the deeper and better portions of my 

 soil the unmanured portion came away better, but there also 

 there was left plenty of margin for showing that judicious forcing 

 will pay best. 



I have no hesitation in saying that the artificial manures I 

 have applied to barley have paid me at least double. Of course, 

 I varied the quantities according to the nature and condition of 

 the soil to which it was being applied, and I do not reckon the 

 bone meal I may have put on for the grass, though in some cases 

 it was in excessive quantity. 



I will now state my experience of this crop with farm-yard 

 manure, and the comparative results between it and artificial ; 

 also the results of farm-yard manure with a nitrogenous manure 

 used along therewith. I have very seldom given farm-yard 

 manure to barley after the turnip crop, as the turnips are always 

 very heavily manured, and the tops left on the gTound when 

 the turnips are pulled, which I set down at least as equivalent 

 to five tons of farm-yard manure per acre, as compared with 

 driving them off. On a farm such as mine, where the half of 

 the fallow break is under potato, there is always a good por- 

 tion of it unsuitable for wheat, I therefore apply from ten to 

 twenty tons of city or farm-yard manure to it, and sow down with 

 barley. 



The following table will show, as nearly as possible, the average 

 expense of manuring with farm-yard and city manure in equal 

 proportions and the cost of application, showing also the cost of 

 three different mixtures of manufactured manures as used against 

 it, and guano used with it : — 



I. 15 tons of farm-yard manure @ 8/ per ton, 

 Cost of cartage and spreading @ 2/6, 



II. The same as No. I., 



1^ cwt. of Peruvian guano, .... 



III. 8 cwt. bone meal @ 8/6 per cwt, . 



1 J cwt. Peruvian guano, 



IV. 6 cwt. of dissolved bones @ 8/, 



V. 5 cwt. of No. I. mixture, mentioned in the barley, 

 List of artificial manure @ 9/7^, . 



No. TI. gave by far the best results of any of the five. The 

 guano, added to the farm-yard manure, started the barley and 

 kept it growing until its roots got a hold of the dung, which was
