MESSRS. EDITORS—You must have suffered at ovemng lectures or sermons from the glaring lights which almost always surround the speaker, and which produce pain in the eyes and drowsiness. Now, in observatories, a single lamp, centrally placed, sends through lenses ot perhaps 1& inches diameter, beams of light to all points in the room, which it is desired to illuminate,—such are the dials of the clocks. The portions of the graduated limbs of the astronomical instruments, &c, are many feet distant from the source of light,—a spherical shade cuts off all the rays except those which are sent through these lenses. Thus a couple of lamps or gas jets on the galleries, one on each side of the preacher or lecturer, might through three or four inch lenses, send two beams to the pages of his book, while the painful lights generally disposed about him, would be removed, much to the satisfaction of his audience, who would not suffer from headache, and who would be less apt to sleep. M. C. ? Washington, D. C, Feb. 20, 1853. [We hope the above suggestions will be acted upon by many of our churches.—ED. An iron foundry has been started at Dese-ret, Utah, for the manufacture ot hollow ware. Saleratus and brimstone are found there in quantities. Literary Notices ANDERSONS AMERICAN VILLA ARCHITECTURE— This is a new work on Architecture, by Charles F. Anderson, of this city, and published by G. P. Putnam & Co., Park Place : it is to be completed in seven parts, each containing three separate designs, and a supplementary number containing working drawings, specifications, &c The style of architecture is entirely different from any that has heretofore been presented in the many works published on the same subject in our country. The author, an eminent architect, has travelled through Europe, and has minutely inspected the architecture of the various nations there ; he has also visited every State and city, fromthe Gulf of St. Lawrence to that of Mexico, and he has come to the conclusion, after thirty yearsstudy, that be has produced a new style of architecture suited to the climate of our country, and the customs and habits of the age This first number presents three designs, each containing two splendid lithographic perspective views, together with sections, for gentlemens mansions. This is, we think, the finest work on architecture that has yet been presented to the American public. THE SOHOOL FELLOW—A Magazine for Boys and Girls, Terms SI per annum ; Nework, C. M. Sax-ton, 152 Fulton street; Charleston, B. F. De Bow ; Chillicothe, ? , Whittemore & Saxton.—The above is the title of a monthly magazine, intended for the rising generation, and is well deserving of the patronage of parents, as auseful and instructive book to placein their childrens hands. In our times, when periodical literature has become so importart and the newspaper and magazine are almost a necessary of life, it is wise for every one from aniODg the hoatof publications that are daily, weekly, and monthly presented to their notice, to select with care those that are worthy of their patronage. If this is judicious in their own case, it becomes a still more imperative duty to use caution and judgment with respect to the works that their children read. Much good or much harm may be done to the tender mind, whilst it unconsciously sips the honey or the distilled poison ; we cannot, therefore, too earnestly call the attention of those of our readers who have families to the necessity of discretion in this respect ; we would therefore particularly recommend to their notice the above periodical, which is expressly intended for the young, and which contains a fund of useful and instructive reading, together with many capital illustrations. As a literary work it has merits of a high order, and although written down to the comprehension of children, its pages show that its writers can, if necest-a-ry, write up to the understanding of those of larger growth. The School Fellow is an ably got up work, and does credit to all concerned about it, whether publishers, editors, contributors, artists, or HieobiMss. Parents cannot subscribe to a better work to place in their children s hands.
