24 FARMERS' AND MECHANICS' JOURNAL. 



min Hale, Principal of Gardiner Lyceum. It is divided into two 

 parts, the first treats of the strength and stiffness of timber, and the 

 second of statics applied to constructions of timber. We have perus- 

 ed this volume with much satisfaction, and recommend it as calcu- 

 lated essentially to aid the operative carpenter in the prosecution 

 of his business. It does not pretend to much originality, and had 

 it done so, we should have thought it a very unfavorable symptom ; 

 much valuable matter has been published upon this subject, but it 

 is usually contained in works which are inaccessible to the ordina- 

 ry workman, on account of their cost ; and which to most of them 

 wear a repellent aspect, in consequence of the extensive use of 

 algebraic formulae : for however desirable it may be, and is, that 

 the mechanic should be well acquainted with the arithmetic of 

 signs, the time is not likely soon to ariive when this knowledge 

 will be general. To the work before us, neither of these objec-. 

 tions can be urged. 



Mr. Hale has made free use of Tredgold, Robison, Barlow, and 

 others, either copying them verbatim, or moulding them so as to 

 •suit his purpose, and has thus produced a work, which, whilst it is 

 moderate in cost, is neat in its execution, and valuable from its 

 matter. The subjects are illustrated by 82 figures, executed with 

 remarkable neatness. We are informed in a note, that " The cuts 

 in this book were made by Mr. L. T. Jackson, of Brunswick, Me- 

 of brass rule, according to a method recently invented by him. 

 These are the first specimens which have appeared in any publica- 

 tion, and this note is inserted, in justice to the author of an inven- 

 tion, which will probably be of considerable importance."

GARDINER LYCEUM. 



The attention of the public is respectfully invited to the Adver- 

 tisement for Winter Classes in the Lyceum, the ensuing season. — 

 Those Mechanics who are desirous of obtaining knowledge, which 

 will be of daily practical use to them, and which can be obtained 

 in few other institutions in the United States, would do well to 

 embrace the opportunities now offered them. The expense, which 

 has hitherto deterred many, cannot now be an objection. Those 

 who are not able to pay for tuition, can have it gratis ; and as it 

 regards the board, it may be paid in whole or part by labor. 



DENTON. 

 This celebrated Bui! of the " Improved Durham Short Horn 

 Breed," so well known among the breeders of fine stock in Massa- 

 chusetts, has, by the politeness and generosity of his former owner, 

 S. WiLLrAMS, Esq., been sent to the Editor. He is now in Gardi- 

 ner, where he may be seen and examined by all who wish. A 

 further notice of him will be given in our next.
