This work was much more voluminous than any of the preceding ones; it was ornamented by some elegant copperplate engravings of landscape scenery, drawn by himself, which, in 1801, were republished, with short descriptions, as a separate work.

Daring the greater part of the year 1806, Mr. Loudon was actively engaged in landscape-gardening; and, towards the close of that year, when returning from Tre-Madoc, in Caernarvonshire, he caught a violent cold by travelling on the outside of a coach all night in the rain, and neglecting to change his clothes when he reached the end of his journey. The cold brought on a rheumatic fever, which settled finally in his left knee, and, from improper medical treatment, terminated in a stiff joint; a circumstance which was a source of great annoyance to him, not only at the time when it occurred, but during the whole of the remainder of his life. This will not appear surprising, when it is considered that he was at that period in the prime of his days, and not only remarkably healthy and vigorous in constitution, but equally active and independent in mind. While suffering from the effects of the complaint in his knee, he took lodgings at a farm-house, at Pinner, near Harrow; and, while there, the activity of his mind made him anxiously inquire into the state of English farming.

He also amused himself by painting several landscapes, some of which were exhibited at the Royal Academy, and by learning German, paying his expenses, as he had done before when he learned French, by selling for publication a pamphlet which he had translated by way of exercise. In this case, the translation being of a popular work, it was sold to Mr. Cadell for 15l. He also took lessons in Greek and Hebrew. The following extract from his Journal, in 1806, will give some idea of his feelings at this period: "Alas! how have I neglected the important task of improving myself 1 How much I have seen, what new ideas have developed themselves, and what different views of life I have acquired since I came to London three years ago! I am now twenty-three years of age, and perhaps one-third of my life has passed away, and yet what have I done to benefit my fellow-men?"

Mr. Loudon, during the length of time he was compelled to remain at Pinner, became so interested respecting English farming, and so anxious that the faults he observed in it should be corrected, that he wrote to his father, stating the capability of the soil, and the imperfect state of the husbandry, and urging him to come to England. It happened that at this period the farm called Wood Hall, where he had been staying so long, was to be let, and Mr. Loudon, Senior, in consequence of the recommendation of his son, took it, and removed to it in 1807. The following year, Mr. Loudon, who was then residing with his father at Wood Hall, wrote a pamphlet entitled "An Immediate and Effectual Mode of Raising the Rental of the Landed Property of England; and Rendering Great Britain Independent of other Nations for a Supply of Bread Corn. By a Scotch Farmer, now farming in Middlesex." This pamphlet excited a great deal of attention; and General Stratton, a gentleman possessing a large landed estate, having read it, was so much interested in the matter it contained, that he offered him a portion of his property at a low rate, in order that he might undertake the management of the rest, and thus introduce Scotch farming into Oxfordshire.

The farm which Mr. Loudon took from General Stratton, and which was called Great Tew, was nearly eighteen miles from the city of Oxford, and contained upwards of 1,500 acres. "The surface," as he describes it, "was diversified by bold undulations, hills, and steeps, and the soil contained considerable variety of loam, clay, and light earth, on limestone and red rock. It was, however, subdivided in a manner the most unsuitable for arable husbandry, and totally destitute of carriage roads. In every other respect it was equally unfit for northern agriculture, having very indifferent buildings, and being greatly in want of draining and levelling." At this place he established a kind of agricultural college for the instruction of young men in rural pursuits; some of these, being the sons of landed proprietors, were under his own immediate superintendence; and others, who were placed in a second class, were instructed by his bailiff, and intended for land-stewards and farm-bailiffs. A description of this college, and of the improve-ments effected at Great Tew, was given to the public in 1809, in a pamphlet entitled "The Utility of Agricultural Knowledge to the Sons of the Landed Proprietors of England, and to Young Men intended for Estate-Agents; Illustrated by what has taken place in Scotland. With an Account of an Institution formed for Agricultural Pupils in Oxfordshire. By a Scotch Farmer and Land-Agent, resident in that County." In this pamphlet there is one passage, showing how much attached he was to landscape-gardening, an attachment which remained undiminished to his death; and how severely he felt the misfortune of having his knee become anchylosed from the effects of the rheumatic fever before alluded to.

The passage, which occurs in the introductory part of his work, is as follows: "A recent personal misfortune, by which the author incurred deformity and lameness, has occasioned his having recourse to farming as a permanent source of income, lest, by any future attack of disease, he should be prevented from the more active duties and extensive range of a beloved profession on which he had formerly been chiefly dependent".

Notwithstanding the desponding feelings expressed in this paragraph, Mr. Loudon appears, from his memorandum books, to have been still extensively engaged in landscape-gardening, as there are memoranda of various places that he laid out in England,Wales, and Ireland, till the close of 1812. Before this period he had quitted Tew; and finding that he had amassed upwards of 15,000/. by his labors, he determined to relax his exertions, and to gratify his ardent thirst for knowledge by travelling abroad. Previously, however, to doing this, he published two works: one entitled "Hints on the Formation of Gardens and Pleasure-Grounds, with Designs in various Styles of Rural Embellishment; comprising Plans for laying out Flower, Fruit, and Kitchen Gardens; and the Construction and Arrangement of Glass-Houses, Hot Walls, and Stoves; with Directions for the Management of Plantations, and a Priced Catalogue of Fruit and Forest-Trees, Shrubs, and Herbaceous Plants; the whole adapted to Villa Grounds from One Perch to One Hundred Acres in Extent;" and the other, "Observations on laying out Farms in the Scotch Style adapted to England".

In the first of these works, the subjects enumerated in the title page are fully discussed; the second contains many interesting particulars respecting the farm of Great Tew rented by himself, and those of Wood Hall and Kenton Lane rented by his father. From this work it appears, that, though Mr. Loudon, Senior, enjoyed but a few months' health after settling at Wood Hall, which he entered upon at Michaelmas, 1807, his death taking place in December, 1809, the estate was so much improved, even in that short period, that it was let after his death for a thousand pounds a year, being three hundred pounds a year more than he had paid for it It also appears that Mr. Loudon entered on the farm at Great Tew at Michaelmas, 1808, and left it in February, 1811; General Stratton paying him a considerable sum for his lease, stock, and the improvements he had effected.
