A PRACTICAL TREATISE ON AGRICULTURE, 
Briefly pointing out certain practices to be adopted, and some to be discontinued, 
WITH A VIEW TO THE IMPROVEMENT OF ARABLE LAND, &c. 
Pamphlet .—52 Papes. 
BY RICHD. W. LLOYD, ESQ. WHITTAKER AND CO. LONDON. 
The intention of the Author of this Pamphlet is to supply those uninitiated in 
the art, with a plain and simple exposition of the principles of practical agricul¬ 
ture, of which great numbers are to this day almost entirely ignorant. From 
what we know of the subject, we think the mode he has adopted is likely to be 
successful. The Author, after a few preliminary observations, treats on Plough¬ 
ing and Cleansing Land, and on the Rotation of Crops, whereon he remarks 
that for heavy land the most judicious crops are wheat, cabbages, beans, oats, 
and clover; for light and dry soils, vetches, barley, buck-wheat, all the variety 
of the green crop tribe, and most of the various kinds of grasses. In a rich 
loam, which is of all descriptions of land the very best, any of the above-men¬ 
tioned plants will thrive well. He next proceeds to remark on the value and 
profit of different plants, and the winter vetch, in his opinion, stands unrivalled, 
not only as it regards present profits, but as a great improver of the land. Tur¬ 
nips come next, being considered preferable to either mangel-wurzel, carrots, or 
parsnips. The two sorts chiefly recommended are the Swede aud Yellow Scotch. 
The Pamphlet treats on Mangel-Wurzel, Carrots, Cabbages, and Potatoes. 
Under the latter head is introduced the comparative value and produce of pota 
toes and turnips. A crop of potatoes is considered very good, when an acre 
yields 400 measures. One measure weighs 105 lbs. which multiplied by 400 
makes a total of 42,000 lbs. This divided by 2,240 lbs. being one ton of 1121bs. 
to the cwt. shews the produce per acre to be 18 tons 1780 lbs. we may say 19 tons. 
And what is this in comparison with the weight of an acre of Swedes or other 
turnips? The crop is but an ordinary one, if it do not weigh 30 tons, for this 
weight may be easily obtained; and, from such land as would yield 400 mea¬ 
sures of potatoes per acre, much more than 30 tons of turnips might be got. 
As food for cattle, sheep, and hogs, turnips answer the best. All kinds of stock 
will eat them without tiring, which certainly is not the case with potatoes,” and 
added to this, potatoes are in their nature heating. The expenses of planting 
and gathering potatoes are more than double the cost of turnips, which leaves a
