448 DnuivnoiuV s Exhibition of Agricultural Productions. 



fifth or miscellaneous class consisted of models of different 

 kinds : straw ropes, wheat straw for thatching, and a great 

 variety of other articles. Among them was a specimen of a 

 beech hedge from Messrs. Drummond's nursery grounds, the 

 details respecting the management of which may prove in- 

 structive to others of the profession. " The mode of rearing 

 this hedge is simply by annually cutting the sides close in, 

 and nearly perpendicular, but never the tops, until they ar- 

 rive at the desired height. Each plant has thus a fine stem 

 (6 inches separate), well feathered, and the hedge presents a 

 close surface of leaves, occupying no more space than a com- 

 mon garden wall. Nine hundred yards of these hedges have 

 been kept from 7 to 8 ft. in height more than 20 years, increas- 

 ing in width only 2 in. or 3 in. Height of the specimen, 7 ft. ; 

 width at bottom, 15 in. ; width at 6 in. from the top, 12 in." 



The sixth class consisted of garden produce, and included 

 numerous specimens of roots, fruits, seeds, &c., and models 

 of moss houses, of "Ellen's Bower" in the island of Loch 

 Katrine, and of a hollow brick wall. The seventh class con- 

 sisted of implements. Among these were Smith of Deanston's 

 subsoil plough, with the following label : — " Used on Deans- 

 ton farm ; drawn by four horses, yoked two and two. A 

 furrow, about 12 in. broad and 2 in. deep, is taken up by the 

 common plough, when the subsoil plough follows, going from 

 16 in. to 18 in. deep from the surface ; will plough a Scotch 

 acre in 9 hours, turning out all the stones not exceeding 

 2 cwt., and completely opening up the subsoil. Cost of a 

 plough, with soam chain and two socks, from 11. to 8/." We 

 wish to call the attention of gardeners to this plough, which 

 we are persuaded they might frequently use to advantage in 

 preparing extensive surfaces for planting. 



The communications occupy 32 pages, and well deserve 

 the perusal of every agriculturist. The pamphlet is so cheap, 

 that every reading farmer should procure it. The following 

 interesting passage occurs at the end of Mr. Smith of Dean- 

 ston's article on thorough drainage and deep ploughing 

 (Mr. Smith is considered one of the most scientific mechanical 

 engineers in Scotland, as well as a man of singular origin- 

 ality and invention) : — 



" The complete drainage of land is the foundation of all 



good husbandry The general improvement of the 



soil of the country would tend to lower the value of high- 

 rented land ; but then the aggregate rental of the kingdom 

 would be greatly increased, whilst the general average cost of 

 the produce would be considerably diminished, affording 

 cheap provisions to the consumer, whilst both the landowner
