as old silver, on the contrary, has sound 

 founaations ; there is no doubt about its 

 date and market value. It is writ so large 

 that he who runs may read. The making of 

 a collection of old silver is literally within 

 the means of the middle-class collector. The 

 author knows his subject well, and treats 

 the same with a breadth which is truly re- 

 freshing in a book for collectors by a col- 

 lector. The text is printed on beautiful 

 light-tinted paper most agreeable to the 

 touch and to the eye, while the inserted 

 plates are printed on the whitest of coated 

 naper. The section relating to hall-marks 

 and date letters is most valuable. The sale 

 prices which are appended give valuable 

 indications of the market during the last 

 few years. 



Chats on Old Earthenware. By Arthur 

 Hayden. New York: Frederick A. 

 Stokes Company, 1909. i2mo. ; pp. 

 496. Price, $2. 

 This beautiful book is accompanied by 

 150 illustrations and tables of over 200 il- 

 lustrated marks. Five years ago the author 

 published "Chats on English Silver" which 

 was warmly received. A great number of 

 readers wrote to the author suggesting that 

 he should write a companion volume deal- 

 ing with old English earthenware. The col- 

 lection of old English earthenware, in the 

 main, is still within the reach of those who 

 have slender purses, while English china 

 within the last decade has reached prohibi- 

 tive prices. After a bibliographical sketch, 

 comes a glossary, then a chapter on "How 

 to Collect, for Beginners," which is ex- 

 tremely valuable. This is followed by chap- 

 ters on Early AVare ; English Delft ; Stone- 

 ware ; Early Staffordshire Ware ; Slate 

 Glazed Ware ; Josiah AVedgwood, Leeds, 

 and other factories ; Transfer Printed 

 Ware ; Staffordshire Figures ; Swansea and 

 other factories ; Lustre Ware ; and Late 

 Staffordshire Ware. There are valuable 

 lists of prices appended to every chapter. 

 The book is very handsomely made and is 

 sure to merit the attention of all collectors. 



Modern Lettering, Artistic and Prac- 

 tical. By William Heyny. New 

 York: William T. Comstock, 1909. 

 8vo. ; 136 pp. Price, $2. 

 This is a book of instruction primarily 

 valuable in the hands of the beginner and 

 of assistance to the experienced workman. 

 "Modern Lettering" essays the subject 

 from the practical standpoint from cover to 

 cover. The author, a man of experience 

 and of artistic temperament, boldly sets 

 forth his ideas and propounds his methods 

 in concise language. Directions even to 

 minute details are given, all of which are 

 valuable to the student. The plates are all 

 on a large scale and the letters are clear 

 and sharp. The French Roman is a new 

 letter in this country, and will be appreci- 

 ated for its refinement, beauty and legibilitv. 



Power, Heating and Ventilation. A 

 Treatise for Designing and Con- 

 structing Engineers, Architects and 

 Students. By Charles L. Hubbard. 

 B.S.. M.E. Part HI.. Heating and 

 Ventilation. First edition. Brattle- 

 boro, Vt. : The Technical Press, 1909. 

 8vo. ; pp. 647. Price, $2. 

 This is a very practical book dealing with 

 all phases of warming and ventilation. 

 Even such subjects as electrical heatimr are 

 taken up. The illustrations are excellent, 

 the expensive but eminently successful wax 

 process being used. The tables are also of 

 great value. The subject is treated with 

 rare discrimination, and the book cannot 

 help but be of great use to all engineers. 



Every room should have a MANTEL 

 of appropriate design 



Wood Mantels 



are made in every architectural style; 

 both in the popular hardwoods and in 

 white finish to match painted or enam- 

 elled woodwork. The illustration 

 shows a wood mantel in the Louis 

 XV style, now so popular for parlors. 

 There are many others to select from, 

 in this and other styles, and a wide 

 range of prices to suit all pocketbooks. 



Why Wood Mantels? 



an illustrated booklet containing many photo- 

 graphs and suggestions will be sent to any 

 one thinking of building, remodelling or 

 decorating. Address

 not if the "something better" costs no more ?
