same work executed by his landlord, with pipes produced by 
himself, but carrying no profit, would cost, as per table, IZ. Is. 1 \d. 
and IZ. \ \s. 9d. respectively. This is a naked expression of the 
facts, and it may be useful as pointing out the absolute saving to 
both landlord and tenant, when the landlord may be enabled, 
from the magnitude of his estate, the presence of suitable clay, 
&c„ to manufacture his pipes, furnish the skill, and undertake a 
systematic drainage for his tenants on a good and cheap plan. 
For the reasons before stated, the cost of main drains and the 
opening out or deepening of ditches is not given in the Table, 
which must, therefore, be regarded as representing simply the 
cost of inch-pipe parallel or general drains irrespective of other 
conduits. 
Ever, my dear Sir, very truly yours,

X. — Letter on Deep Draining. By the Right Hon. C. 
Arbuthnot. 
To Josiah Parkes, Esq. 
Dear Sir, — You desired to be informed of the particulars of the 
experiment I communicated to you of laying land dry by drains 
four feet deep. 
I was induced to make the experiment from reading an article 
written by you, and which was published in the Journal of the 
Royal Agricultural Society of England, vol. v. p. 1 19. 
Two paddocks of old grass land, containing together 7 acres, 
the soil being a very stiong clay, and which had been attempted 
to be drained, but without effect, by shallow drains, appeared to 
be well calculated for the experiment. I sent directions to my 
bailiff first to pare the turf of the two paddocks preparatory to 
burning it ; and, this being done, to sink drains in each furrow 
four feet deep, and to lay pipes at the bottom of each drain. The 
shallow drains had been drawn diagonally across the land, but 
the deep drains were laid down each furrow, the distance between 
the furrows varying from 45 to 25 feet. 
At the time that the work was in progress (commenced since 
January last) there was scarcely even a single drop of rain ; but 
when it was completed (about six weeks ago) there were some 
very heavy showers, and it was not long before the effect of the 
4-feet drains was ascertained. I ought here to mention that the
