placed too great reliance on the opinions and assertions of Mr. Tull. We both suffered severely in pocket, by persevering too long in, and acting too extensively upon, the plan of drilling wheat at wide intervals, as laid down by Tull. I do not mean to insinuate that Mr. Tull ever stated the amount of his crops to be better in quality, or more in quantity, than they really were; but I have no hesitation in saying, that the climate of England must have been very different in the time of Mr. Tull from what it was in the days of Mr. Cobbett and Mr. Hunt, to have produced either the quantity or the quality of wheat which Mr. Tull says was produced per acre upon his farm, according to his system. When I found the practice fail, and that wheat was blighted upon the high hills and cold soil of Hampshire, I took a farm into my own hands at Upavon, in Wiltshire, for the purpose of giving the system a fair trial. Nay, so convinced was I of the truth of the principles laid down by Tull, respecting the food of plants, and such reliance did I place upon the truth of his assertions, that I persevered one or two years after Mr. Cobbett had given the thing up as a hopeless and losing speculation. I mean to be understood only as far as relates to the drilling of wheat at four feet intervals, to plough between the rows; for the practice certainly succeeds with turnips, to the full description of any thing given by Tull. Mr. Cobbett, I see, has lately republished the work of Tull, and I therefore caution such of my friends as may read that work, not to be led away with the beautiful theory of Mr. Tull, so as to adopt the plan of drilling wheat to any extent. In certain soils it may succeed with barley; but in these times it is too expensive a system for any one to pursue with advantage to any extent. Those who have good light ploughing sandy, or sandy loam soils, will find it answer their most sanguine expectations, in turnips of any sort, and particularly in the cultivation of Swedish turnips. Of course, I only address myself to those farmers who superintend the whole progress of drilling, transplanting, hoeing and ploughing; for Tull's is not a system to answer if trusted to servants. I can only say for myself, that I adhered to the system so long, that I believe I was minus by it, first and last, above a thousand pounds, and I believe Mr. Cobbett was a loser to an equal degree.
