OIL-CAKE, 419 



(joKE has procured one from Mr. Burrel, of Thet- 

 ford, wliich worked while I was at Holkham, to the 

 great satisfadion of every one who saw it, delivering a 

 constant stream of powder so regularly, tliatno doubts were 

 entertained of the great success of the invention. It con- 

 tains alternate divisions, with large and small cnps for the 

 delivery of both cake and seed into the same drills. In 

 this way a ton does six acres, instead of three or four in 

 the common method. In a letter I afterwards received 

 from this very able cultivator, he informed me that the 

 experiment answered to his satisfa6l:on. 



Mr. Hill, of Waterden, has much doubt of the bene- 

 fit of this manure, and thinks that ic is often used (the 

 great expense of it considered) to loss. For the last 

 three years it has decreased in goodness, by reason of the 

 increased power of the mills, exertions caused as he thinks 

 by the great demand. It should not be used in less quan- 

 tity than two tons to five acres ; and always for turnips in 

 preference to wheat. 



Mr. Johnson, of Thurning, finds tliat from one-third 

 to half a ton per acre for turnips, will, in a wet season, 

 heat every thing. It ought to be sown the first week in 

 May, if possible ; all ideas of putting it in at the same time 

 with the seed, he thinks erroneous • he has seen it quite 

 lost thus : in dry seasons it has no effedt. Of this manure 

 Mr. Johnson uses much. He thus expresses himself in 

 a letter he favoured me with: 



*• Rape-cake is an excellent manure for turnips, and 

 does not subjefl them to mildew; they will grow longer 

 than from any other manure ; the turnip that grows most 

 after Michaelmas is always of the best quality. Malt 

 combs quick to bring the turnip to the hoe ; rape-cake 

 flow i where both are used they should be sown together,
