TRED GOLD'S CARPENTRY.

ELEMENTARY

OF

PRINCIPLES

CARPENTRY.

A Treatise on the Pressure and Equilibrium of Timber
Framings, the Resistance of Timber, and the Construction of
Floors, Roofs, Centre Bridges, &c.; with Practical Rules and
Examples. To which is added an Essay on the Nature and
Properties of Timber, including the Methods of Seasoning, and
the Causes and Prevention of Decay, with Descriptions of the
Kinds of Scantlings of Timber for different Purposes, the specific
Gravities of Materials, &c. Illustrated by twenty-two engravings
and several wood cuts.

BY THOMAS TREDGOLD, Civil Engineer.

"This work forms an excellent elementary manual for the carpenter, as
well as a valuable book of reference for the architect or engineer.

"The principles laid down by Mr. Tredgold, relating to that branch of
the art which is particularly directed to the support of pressure, are all
founded upon the immutable laws of mechanics, and explained with great
perspicuity. The strength of various kinds of timber to resist tension, com-
pression, or cross strains, is fully investigated, and copious tables are given,
exhibiting the results of experiments on the strength and cohesion of almost
every description of wood.

"One of the most important divisions of the work is that which is devoted
to the investigation of the nature and properties of timber. Many of the
curious and interesting facts connected with the growth of trees are men-
tioned, and much valuable information is furnished on the subject of felling
and seasoning timber, the prevention of decay and dry rot, and the durability
of wood in different situations."-Journal of the Franklin Institute.

WITH NEARLY ONE HUNDRED HUMOROUS ILLUSTRATIONS.

It would be difficult to find in the language a volume containing a greater amount of drollery, or one better calculated to drive away the blue devils. Let all hypochondriacs throw away their physic, and in lieu of it take a dose of TOM HOOD, and the cure is certain.

CHARCOAL SKETCHES;

OR,

SCENES IN THE METROPOLIS.

BY JOSEPH C. NEAL.

With ILLUSTRATIONS by D. C. JOHNSTON.

"It is made up of a series of off-hand sketches of real life; which, for humour, nature, and graphic force, are, we venture to assert, equal to the best passages of the celebrated Pickwick papers. Several of these sketches are indeed inimitable. Nothing superior in the same style is to be found in modern English literature."-Pennsylvania Inquirer.

"This volume is a right merry production, from the pen of J. C. Neal, who peculiarly excels in that most difficult path of literature-the hu morous. The engravings with which it is enriched, are 'Charcoal Sketches' of no common character. They are truly racy and laughable."-Saturday Courier.

"A collection of sketches humorously delineated and dashed off in a style of pleasantry from a spirited pen."-Public Ledger.

"The 'Sketches' are so graphic, and at the same time so quaint, that the illustrations, though sufficiently well executed, add little or nothing to the value of the tone."-Com. Herald.

In One Volume, 8vo.

"But we are confident that had Mr. Prior done or should do nothing else, the services he has rendered to literature, by recovering and recording these beautifully characteristic effusions, would be enough to secure honour to his memory; and the volume which we now close, will ever constitute one of most precious' wells of English undefiled.""-London Quarterly Review.

THE ART OF DINING,

AND

THE ART OF ATTAINING HIGH HEALTH:

WITH A FEW HINTS ON SUPPERS.

BY THOMAS WALKER, ESQ.

One small Volume.

"Anybody can dine, but very few know how to dine so as to ensure the greatest quantity of health and enjoyment,

"As dining is an occurrence of every day, or nearly so, of our lives, and as our health and spirits depend in a great measure upon our vivid enjoy. ment of this our chief meal, it seems to me a more worthy object of study than those unreal occupations, about which so many busy themselves in vain.

"I think the art of dining properly understood, is especially worthy the altention of females of all classes, according to their respective means. It comes peculiarly within the province of domestic economy, and is indeed one of its most important features.

"The art of dining and giving dinners is expounded with such extent of knowledge, such comprehensiveness of view, such soundness of principle, and delicacy of taste, that we shall best discharge our duty to our readers by making it one of the leading objects of this article.

"Whatever is worth doing at all is worth doing well.'

"We presume no one will deny that dining is among the things worth doing occasionally."-London Quarterly Review.
