496 On the Composition of Linseed Oil- Cake, ^^c. 



their composition is liable to very considerable variation. Neither 

 in the peas nor beans does the average composition ap])ear to 

 fluctuate with the variety, but to rise or fall in obedience to laws 

 which the analyses are not intended to elucidate. 



Note hy Mr. Pusey. 



I am glad to be able to report favourably as to the discovery 

 accidentally made by me (as mentioned in the last number), that 

 sheep, when at turnips, can be fed on rape-cake without the ad- 

 mixture of linseed-cake. This autumn I have kept 700 fatting 

 sheep in this way, on rape-cake, with entire success ; and in order 

 to be certain that the progress in condition was equal, I put up 

 two little lots of ten sheep each, keeping one upon rape-cake and 

 the other on linseed-cake. Not the slightest difference could be 

 perceived between the two lots. As the best linseed-cake costs 

 71. lOi'., and the best rape-cake only 41. \0s. per ton, the saving 

 in the production of mutton, arising from the use of rape-cake, is 

 really considerable. In that of beef it is not so much, as I do not 

 find that my beasts like a larger proportion of rape-cake to linseed- 

 cake than pound for pound of each. 



XXV.— -0y^ the Advantage of Deep Drainage. From the Right 

 Hon. C. Arbuthnot. 



To the Secretary. 



Walmer Castle, October 9, 1848. 



My dear Sir — No consideration could induce me at any 

 time to engage in litigious controversy upon any subject whatever, 

 and much more unwilling should I be upon the question, whether 

 it be the more advisable to have deep drains or shallow ones. 



If, therefore, I feel inclined to make some observations upon 

 the subject of drainage, 1 can assure Mr. Bullock Webster, 

 whose article I have read in the Royal Agricultural Journal of 

 August last, that, to use his own words, I am neither of the deep 

 nor of the sh^Wow faction ; but that I will confine myself to 

 stating what has been my own experience, and what that of friends 

 to whom I had communicated the result of my practice. 



I had happened some years ago to read an article in the 

 Royal Agricultural Journal on deep drainage by Mr. Josiah 

 Parkes, and it struck me to be so reasonable that I resolved to 

 try the plan upon some very stiff clay on the farm I cultivate in 

 Northamptonshire. I wrote to my bailiff, Mr. Andrew Thompson,
