to the arts : it treats of lightning conductors, copper sheathing, submarine 

 operations, electric moving power (in lieu of steam, &c.), electro-locomotive 

 power, electrical telegraph, electro-metallurgy, electro-gilding and plating, 

 electrotype, and electrotint. Such are the wonders of electricity ! Passing 

 over a number of articles, we come to Art. xv,. Public Improvements, in 

 which the new churches and other public buildings erected throughout the 

 country are noticed, and beautiful engravings given of Wilton Churcii, near 

 Salisbury, in the Lombardic style, Messrs, Wyatt and Brandon, architects, a 

 strikingly original edifice ; Christ church, Broadway, Westminster, in the 

 latter period of early English, Ambrose Poynter, architect ; Wesleyan Theo- 

 logical Institution, Richmond, A. Trimen, architect ; Cambridge County 

 Courts, in the Palladian style, Messrs. Wyatt and Brandon, architects ; and 

 Brunswick Buildings, Liverpool, A. and G. Williams, architects, a building in 

 the Italian Palazzo style, intended to be let out as offices to diiFerent occupiers. 

 As heretofore, vre strongly recommend the Companmi to every gardener who 

 can aiFord it. 



MISCELLANEOUS INTELLIGENCE. 



Art. I. General Notices. 



Use of Sulphate of Ammonia in Agriculture. — For the full developement of 

 the capacity of the soil, and to afford a greater amount of nitrogen than what 

 is afforded either by the ordinary manures, or the ammonia, &c., of the at- 

 mosphere, sulphate of ammonia has been introduced, and found to be a most 

 valuable auxiliary, as a top dressing, to the farmer. It has been found to 

 impart a greater degree of fructification to grass, wheat, and other grain, than 

 any other dressing yet discovered, and at a less cost by 50 per cent. 



The mode of application, as adopted by Mr. C. Hall, of Havering-atte- 

 Bower, Essex, is as follows : — 



Having selected several fields of grass, peas, turnips, and wheat," he had 

 sown broadcast on parts of these fields in quantities, at the cost of 5s. 3cL, 

 lis. M., and 2\s. per acre; the sulphate having cost him 17^. per cwt. 



The produce was kept and threshed separately, when the increase from the 

 wheat-land was found to be as follows : — 



The part that was sown at the rate of 5^. 3c?. per acre gave an increase of 

 three bushels ; 11*. id. gave six bushels; and 21*. upwards of nine bushels; 

 besides a considerable increase of straw. {P/iil. Mag. for Deceml)er, 1842, 

 p. 489.) 



Agricultural Implements. — The improvements which are constantly making 

 in agricultural implements are still greater than those which are taking place 

 in the culture of corn and green crops. The Scotch swing plough is no 

 longer considered the best implement of the kind, but one has been found 

 requiring considerably less draught. For measuring the power required to 

 draw any implement, we have Cottam's Draught- Gauge, allowed by Mr, Pusey 

 to be the best machine of the kind. We have also Cottam's Grubber, which 

 is a great improvement on Finlayson's Harrow ; Cottam's Revolving Dibble, 

 for dibbling wheat or beans ; Cottam's One-Row Drill, for manure and seed ; 

 and Cottam's Apparatus for hatching and rearing Game and Poultry. But, 

 perhaps, the most remarkable agricultural machine of the present time is 

 one imported from France, and to be seen in operation on the premises of 

 Messrs. Graham and Co., Malin's Wharf, Fore Street, Lambeth, which 

 completely cleanses damaged wheat, and also renders wheat that has been 

 injured by the weevil, not only perfectly free from that insect, but weevil- 

 proof for the future. The process would be too tedious to describe here ; 

 but it is completely effective, and of immense importance with reference to 

 the preservation of corn in granaries. Whoever wishes to know all that is
