Without stopping to trace the history of British Agriculture, we venture to offer an opinion which we believe will be acquiesced in by those most familiar with the subject--that, while modern times have contributed not a little to our knowledge of the principles and theory of agriculture, they have done infinitely more to advance the improvement of the practice of agriculture.[9] We say so, without at all intending to disparage the discoveries of Chemistry and Vegetable Physiology. From these sources we expect much more important services, in advancing the art of husbandry, than certainly they have ever yet rendered. [9] Those acquainted with the writings of Tull, Arthur Young, Marshall, and Elkington, must know that, although not exempt from errors, they evolved the leading principles of a right agriculture. Indeed, we would seem almost to be recovering only the lost principles and practices of the Roman farmers of old. They seem to have known the mode of manuring ground by penning sheep upon it--nay, what will astonish Mr Mechi, they practised the plan of feeding them in warm and sheltered places with sloping and carefully prepared floors, upon barley and leguminous seeds, hay, bran, and salt. They knew the advantage of a complete pulverisation of the soil, and the necessity of deep ploughing. Their drainage was deep, and if Palladius does not mislead us, they seem in certain cases to have employed earthenware or tile-drains. But to those who wish to know more of Roman husbandry, and who may not have leisure or opportunity to consult the originals, we have great pleasure in recommending Professor Ramsay's (of Glasgow) paper entitled "Agricultura," in the last edition of _Smith's Dictionary of Greek and Roman Antiquities_,--an admirable specimen of condensed erudition.
