COMPRESSED AIR, ITS PRODUCTION, USES. AND APPLICATIONS, 

 Comprising the Physical Properties of Air, from a Vacuum to its Liquid State, 

 itsThermodyraanics, Compression. Transmission, and Uses as a Motive Power. 

 By Gardner D. Hiscox, m. h. New York : Norman W. Henley & Co., igoi. 

 [Cloth. 8vo. pp 82?. Price, $5.] 



THIS work is not only the most comprehensive, but it is 

 practically the first, devoted to the commercial uses of 

 compressed air, especially in its application to the mechanical 

 arts, outside of occasional papers presented to engineering so- 

 cieties or special articles in various technical journals. While 

 the use of air in its lower condition of compression for power 

 and for mechanical purposes has been known from the earliest 

 ages, the results of the development in this field during the 

 past few decades have well nigh revolutionized some branches 

 of engineering, and greatly facilitated the reduction of cost of 

 mechanical work in many important departments. 



The author of this work appears to have devoted many years 

 to the collection of the material which he has condensed within 

 it. while filling an editorial position. The result of such delib- 

 erate preparation is to be found in a concise, readily compre- 

 hensible style, and the arrangement of the chapters in such 

 sequence as to prove most convenient for the student of his 

 subject, or for him who uses the work only as a book of refer- 

 ence. 



This volume contains forty air tables, involving calculations 

 of use in arranging for the compression of air, as well as for the 

 utilization of its countless applications. There are also no 

 fewer than 545 illustrations, including both compressors and 

 pneumatic tools, indicating the application of compressed air 

 to almost every conceivable industrial purpose. It will prove 

 of interest to rubber manufacturers to know how many various 

 forms of pneumatic tools there are, the utility of which de- 

 pends upon the employment of rubber hose for the transmis- 

 sion of the air. 



This new demand for hose, by the way, has resulted in the 

 necessity for hose capable of meeting new requirements, and 

 has formed an element in the trade of no small importance to 

 the rubber industry. Another important use for rubber hose 

 has occurred in connection with railroad air brakes, and we 

 notice that in the list of patents issued in the United States on 

 compressed air and its appliances, the author has included 

 some pneumatic tires, which form a third important branch of 

 rubber production based upon the modern uses of air.

A READABLE narrative by an American mining engineer of 

 many years experience in the countries named, with incidental 

 accounts of their mineral and other resources, which he re- 

 gards as exceeding valuable. In view of the rate of destruc- 

 tion of the Caucho trees, he thinks it would be advisable — and 

 profitable — to form plantations.

DEATH OF GEORGE P. DODGE. 



GEORGE POMEROy DODGE, president of the Mineral- 

 ized Rubber Co. (No. i8 Cliff street, New York), died on 

 June 21, at his home in Great Neck, Long Island, after an ill- 

 ness of only four days, of pneumonia. Born in Pittsfield, 

 Massachusetts, in 1837, Mr. Dodge traced his lineage back on 

 several lines to the first settlers, he being eighth in descent 

 from William Dodge, who came to Salem in 1629. His great- 

 great-grandfathet was General Seth Pomeroy, of the French 

 wars and of Bunker Hill fame. In 1851 his father, N. S. Dodge, 

 went to England as commissioner to the great London Exhibi- 

 tion, and for some years remained abroad with his family. 

 George P. Dodge became interested in the India-rubber in- 

 dustry, being at onetime connected with Charles Macintosh & 

 Co., at Manchester. Later he returned to America and estab- 

 lished himself as a rubber goods merchant, his business becom- 

 ing incorporated under the laws of New York state in March, 

 1886, as the Mineralized Rubber Co. The business will be 

 continued by those who have been most closely connected with 

 Mr. Dodge in its management. The former secretary of the 

 company, John Schreppner, has been elected president, and 

 William A. Dale, who has long been in charge of the order de- 

 partment, becomes secretary. Mr. Dodge's final illness devel- 

 oped very suddenly, he having visited his office as usual as late 

 as Tuesday of the week in which he died on Saturday. The 

 interment occurred on Monday at Great Neck, at which place 

 Mr. Dodge had resided for twenty-five years. The deceased 

 was a brother of Colonel Theodore A. Dodge, who for many 

 years past has also been interested in the rubber trade.
