74 NOTES* 



367 The most proper and effectual tethers are made of iron chains, the links 

 short, and two swivels to each chain, to prevent them from twisting. Those 

 for cattle should be five yards long, with a strong leather strap and buckle, to 

 fasten to the fore leg of the animal, near the hoof: those for sheep, may be 

 much lighter, and only three yards long, with belts to fasten round the neck. 

 The tether is secured by a large iron pin, on the head of which, is a large 

 swivel, which should play round the pin freely, otherwise the chain is apt to 

 get entangled. Communication from Edward Burroughs, Esq.

 Aberdeenshire, p. 357, &c. 



369 Lord De Vesci has had beef of better quality, and fed in a shorter time, 

 by this system, than by any other he ever tried ; and he is now improving some 

 inferior land, on the principle of tethering. 



370 This practice is recommended as fit to be adopted in the following 

 cases : 1. When grass-lands are not fenced off from the adjoining fields in til- 

 lage 2. When there are young plantations in the neighbourhood of grass- 

 lands, which cannot, without great expense, be secured from trespass j 3. 

 When extensive fields are to be partly grazed ; which cannot be so convenient- 

 ly divided, so as to separate the grazing, from the arable land ; and, 4. When 

 the grass is too short to be cut. 



37 1 Communication from Edward Burroughs, Esq. Mr Burroughs tether- 

 ed seven sheep per acre in spring ; and finding that there was better grass in 

 the field in the middle of May, than when they were first turned on it, he was 

 obliged to put two sheep more per acre to keep down the grass, in a state fit 

 for that species of stock. In the Highlands of Scotland, they contend, that 

 sheep, when tethered, fatten more rapidly than in any other manner.

373 Sometimes strong nets are made use of; but hurdles are preferable, un- 

 less the sheep are very tame.

380 Report of the Norman Islands, p. 1 13. On the recommendation of the 

 British Board of Agriculture, lucern has been introduced into our East Indian 

 possessions ; and potatoes are now more extensively cultivated there than for- 

 merly. Both are likely to prove most valuable productions in those countries. 



381 There is every reason to believe, that the common, or old rye-grass, is 

 inferior to the new varieties. 



382 Cock's-foot is cultivated to a great extent, and with astonishing success, 

 at Holkham. The quantity of sheep kept upon it, summer and winter, is quite 

 surprising ; and the land becomes renovated, by laying two or three years under 

 grass, and enriched by the manure derived from the sheep. Communication 



from Mr Blaikie, at Holkham. 



383 Curwen's Report, p. 42. Cock's-foot does not suit low land, as in such 

 situations, it is apt to grow too coarse. Mr Fall a strongly recommends the 



festuca pratensis.

385 Mr George Sinclair states it as the result of his experiments, that no 

 grass is so well suited for all purposes as cock's- foot. A new variety of the lo- 

 lium perenne, (rye -grass), has been lately offered to the experimental farmer, by
