front and a deep recess at the opposite extremity. It is eievated upon a 

 stvlobate, which irffords a sufficient height for Schools and Class-rooms under 

 the whole area. The Portico is approached in its whole extent by a flight of 

 nine steps; the columns are 2 feet 10 inches diameter at the base, and the 

 Eustyle intercohimination is adopted : it projects eleven teet. and is connected 

 with the end of the building by sqirre pillars, with corresponding antae at 

 the four angles of the building. The flanks are brought out to the face of 

 the antie, and have each five large semi-circular headed windows, with 

 archivolts springing from continuous impost. The whole entablature of the 

 order is continued round the building. A large arch under the Portico leads 

 into a recess, which affords access on each side to the Lobbies, Staircases, 

 and Chapel, The entrances to the Schools are screened in the tront by a 

 bulustrade. The Chapel is 70 feet long, 45 feet wide, and 42 feet high, 

 including the lobbies and entrance recess, over which the gallery is continued. 

 The recess is filled by a Vestry, and gallery over, which is 

 the body of the Chapel by a bold elliptical arch springing from the impost. 

 The Chapel is calculated to seat 700 persons, and admits of the acci 

 tion being increased one half by an extension of the end gallery, and the 

 addition of other galleries on the sides. 



Lifbig's Compost Manure. — This distinguished chemist gives the fol- 

 lowing description for preparing a compost manure, which is adapted to 

 furnish all the inorganic matters to wheat, oats and barley ; it is made 

 ",y mixing equal parts of bone dust and a solution ot silicate of potash, 

 (known as soluble glass in commerce.) allowing this mixture to dry in the air. 

 and then adding ten or twelve parts of gypsum, with twelve parts of common 

 salt. Such a compost would render unnecessary the animal manures, which 

 act by their inorganic ingredients. The silicate of potash employed in the 

 preparation of the compost, must not deliquesce on exposure to the air, but 

 must give a gelatinous consistence to the water in wh'ch it is dissolved, and 

 dry to a white powder by exposure. It is only attractive of moisture when 

 an excess of potash is present, which is apt to exert an injurious influence 

 upon the tender roots of plants. In those cases where silicate of potash 

 cannot be procured, a sufficiency of wood ashes will supply its place." 



Birmingham Canal Navigations.— The Bentlcy Canal, which has lately 

 been executed by this company, under the direction of their engineers, 

 (Messrs. Walker and Burgess,) was opened for traffic on the 28lh of April. 

 It connects the summit level of the Wyrley and Kssigton Canal, near Wed- 

 nesfield, with the Walsall, or lower level of the Birmingham Canal, near 

 Darlaston. and both shortens the distance from the Walsall level to Wolver- 

 hampton, and opens up the nvnes about Willenhall and Bentley. Although 

 the weather was unfavourable, a considerable number ot the committee and 

 principal officers of the company were present; R. Scott, Esq., M.P., acting 

 as chairman pro tern. In proceeding along the line in the company's pleasure 

 boat, the committee complimented Mr. Walker on the excellence of the work 

 done by the contractors, and expressed much satisfaction at the quickness, and 

 at the same time, the steadiness with which the boat rose in the iocki. The 

 total distance between the two canals, nearly 31 miles, and 10 lucks, (6 ft. 6 

 in. each r se) was performed by two horses in 57 minutes, the time occupied in 

 passing through each lock having only been 45 seconds. The advantage of 

 speed and steadiness combined, in working these locks, has been attained by 

 making large paddles with improved machinery, and by introducing the 

 water through culverts, extending under the side walls for their entire length, 

 having a number of long shallow openings into the locks. 



Iron Ships.— The Iron Queen.— We find that iron as a material fur ship- 

 building is fast gaining ground. For steamers iron has been a favourite for 

 some lime past, and there is not now one wooden steamer building at this 

 port, while we observe there are two iron ones of the first class neaj 

 pleted, ami we understand contracts are made for the building of three more. 

 We are also now satisfied that the only objection to sailing vessels of iron — 

 namely, the getting foul during a foreign voyage— is completely removed. 

 This is proved by the result of two voyages h\ the Iron Queen. This lark. 

 of 350 tons register, left the river Tyne in February, 1M2, with 424 tons of 

 coals for Havannah, whence she went to Mobile for a cargo of cotton for 

 this port. She has now coi pleted another voyage, from this port to Gal- 

 veston, in Texas, carrying 30U tons of coals out and a full cargo of cotton 

 home. She had been in the graving dock, where she was visited by many 

 persons, and she is found not to have strained a single rivet, although she 

 struch heavily on Galveston bar. There is no appearance of corrosion, the 

 red lead being fresh on the plates, and neither shells, barnacles, nor any 

 foulness was on her bottom. This desirable result is caused by the single 

 application of a compound of tallow, bright varnish, arsenic, and brimstone, 

 which effectually destroys marine vegetable and animal substances. — Liver-
