EXPERIMENTS ON TUl-'NIPS.

In 1882, as before mentioned, 7 and 8 were on the wettest part 

 of the soil, and for that reason this trial is not satisfactory. It 

 may be noticed that plot 22, with potash, nitrate of soda, and a 

 mixture of ground aud dissolved mineral, though it looked 

 better in August, ultimately yielded 30 cwt. au acre less than 

 plot 11, which received the same manure, with the exception of 

 the phosj)hates being all in the dissolved state ; but in the 

 absence of confirmatory evidence, this result is not of much 

 value. In 1883 the average yield from plots 7, 21, 22, and 8, 

 with superphosphate and ground mineral mixed, is 572 '5 cwt. 

 per acre, w^hile the average produce from the corresponding 

 plots 4, 20, 23 and 13, with equal money value of superphos- 

 phate alone, is o84'7 cwt. The mixture, though better than 

 ground mineral alone, gives no encouragement to use it in pre- 

 ference to superphosphate. 



III. Artificials alone against Dung ivith less Artificials. — 

 In Table XIV. only plots to which phosphoric acid has been 

 added in some form are included, for no one would attempt to 

 grow turnips on undunged land wdthout giving phosphates. 

 The dung was not analysed, but was of excellent quality. For 

 both crops it was made during the preceding winter by twenty 

 feeding cattle in stalls and six horses. The cattle got 60 lbs. of 

 pulped turnips mixed with 15 lbs. hay and straw chaff, also -1 

 lbs. linseed cake and 2 lbs. light oats per diem, and the horses 

 were liberally fed. The liquid as well as solid manure from both
