io Cultivation of a Moor in Cornwall. [april, 



to plough across the slope, commencing at the bottom. The 

 furrows, which were about n in. wide, and 6 to 7 in. deep, 

 were all turned one way, to ensure the complete inversion 

 of the sod. 



The difficulty of securing adequate drainage was sur- 

 mounted by using a Case Road Grader imported from the United 

 States. This implement is widely used in the United States 

 and the Dominions and was found quite effective for making 

 open drains. It may also be usefully employed in cleaning 

 out existing open drains and ditches. 



After ploughing, the land was rolled twice, in order to ensure 

 that the herbage should remain buried as far as possible. It 

 was then twice disc-harrowed. 



At this stage the land was allowed to lie fallow for 9 months 

 until the following April, receiving no treatment except an 

 application of lime at the rate of 1 J tons per acre. It was then 

 again disc-harrowed twice with a Fordson tractor. The 

 Committee decided to try seven different kinds of oats, a plot 

 being set aside for each kind. Each plot was divided into three 

 sections, in order that manurial tests could be made at the 

 same time. The first section was manured with a mixture 

 of 5 cwt. superphosphate and 1 cwt. sulphate of ammonia 

 per acre (mixture " A ") ; the second with 3 cwt. superphos- 

 phate and 1 cwt. sulphate of potash per acre (mixture " B ") ; 

 and the third was left unmanured. 



Sowing was carried out during the middle of May, at the rate 

 of about 4 bush, per acre ; this was rather late, owing to wet 

 weather and a difficulty in obtaining seed. The seven varieties 

 sown were Victory, Golden Rain, Potato, Yielder, White 

 Canadian Banner, Cornish, and American Black Tartar, the 

 last three being obtained from local sources. Yielder and 

 Golden Rain gave the best crops, followed by Victory and 

 Potato. Yielder, however, had the advantage of being the 

 first seed to be planted, while Potato was planted last. The 

 Cornish varieties were all very late in maturing, and, moreover, 

 did not give very heavy yields. 



As regards the effect of manuring, " A " mixture gave the 

 best results, possibly owing to the effect of the sulphate of 

 ammonia, which enabled the crop to make a good start before 

 the dry weather set in. " B " mixture gave fair results, the 

 straw being of good length, but the crop was neither so thick 

 on the ground nor so heavy in the ear as in the case of the 

 " A " mixture plots. The unmanured sections in every case 

 gave poor results.
