rectify this various green crops were sown 

 and ploughed under, and other treatment 

 given to restore the humus. 



Another question being tested was the 

 length of time liberal applications of 

 barn-yard manure on the soil would con- 

 tinue to affect the subsequent crops put 

 in without manure. Nothing definite on 

 this point is yet determined, as only two 

 crops have been grown since. The use 

 of mineral super, alone, at rate of 5001b. 

 per acre, does not appear to have a marked 

 effect on wheat ; but contrary to what 

 might be expected, the continued appli- 

 cation year after vear of an incomplete 

 fertiliser like super, does not appear to 

 have resulted in smaller returns. The 

 average yield of this plot for the first ten 

 years was 11 bushels, 48 .o/lOlb. per acre ; 

 for the thirteenth year ithe second crop 

 put in without additional mapure), the 

 yield was 11 bushels 551b. per acre. 



Another plot receiving the same treatment 

 shows the same general results, but the 

 returns are somewhat better, the ten 

 years' average being 12 bushels 33 8/lOlb., 

 and the thirteenth crop 14 bushels 401b. 

 The average for thirteen years of the two 

 plots manured with super, is only 2 

 bushels above the average of the two un- 

 manured plots. In the tests with oats 

 and barley the results have been some- 

 what similar, though the yields all round 

 are higher, and the super, has been more 

 profitable. With the returns from oats 

 the extra yield averaged about 9 bushels, 

 and with barley about 6 bushels, more 

 per acre than the average of the un- 

 manured plots. 



Right through the whole series of ex- 

 periments the application of 15 tons per 

 acre of farmyard manure has given the 

 best return. 



Mr. Tom Hall's Oevons, 



THE above is a picture of some of Mr. 

 T. W. J. Hall's Devons. The troop 

 is now getting pure-bred, nearly all being 

 of the fourth or fifth strain, and after the 

 sixth a herd is considered to be pure-bred. 

 Several attempts were made to get the 



cow with the uncharacteristic white 

 markings— one of the exceptions — to take 

 up a less obtrusive position, but she was 

 not to be thwarted. For a full account 

 of Mr. Hall's troop and for his views on 

 cattle management see No. 1, Vol. IV.
