""pO the Editor of The India Rubber World: Dear Sir — It 

 ■'• is not my intention, or desire, to engage in a long drawn- 

 out discussion, but I shall feel grateful to you for a few lines 

 of your valued space to enable me to reply to the letter of W. T. 

 Bonner in your last issue, criticising my article on "The Signifi- 

 cance of Gravity in Rubber Manufacture," which appeared in 

 the June issue. 



Mr. Bonner has apparently failed to realize that my remarks 

 were confined purely to the discussion of the interpretation of the 

 gravity, not in manufactured articles, but in compounding in- 

 gredients such as shoddies, mineral filler, substitutes, etc. I 

 purposely avoided discussing the significance of gravity in manu- 

 factured articles, wishing to confine myself entirely to the rav\r 

 materials. 



Mr. Bonner is undoubtedly correct in saying that the apparent 

 gravity is an important consideration in manufactured articles, 

 but his reasons for this statement are, to my mind, somewhat 

 misleading. Except in a very few extreme cases, of which the 

 manufacture of sponge stock is an example, it is always de- 

 sirable that the manufactured article have a minimum of porosity. 

 In other words, that the difference between the actual and ap- 

 parent gravities be as small as possible. It is useless to try to 

 control the uniformity of the manufactured articles from the de- 

 terminations of apparent gravity, because variations in the actual 

 gravity of the raw materials may compensate irregularities due 

 to variations in the apparent gravity of the manufactured article. 

 The result would be that although the apparent gravity would be 

 constant, its porosit\- could vary. Of course, if in each case the 

 actual gravity had also been taken, this variation would be ob- 

 served, but this necessitates a full understanding of the relation- 

 ship of actual and apparent gravity. 



On the other hand, apparent gravity is of the greatest import- 

 ance from the standpoint of a factory cost department. In this 

 case actual gravitv' is irrelevant. For all goods that are sold by 

 bulk or linear measure, the manufacturer is not interested in the 

 weight per pound of his compound, but in the weight per unit 

 of volume. This is a point which many manufacturers do not 

 realize, yet it repeatedly happens that of two compounds, that 

 one, the cost of which is higher, may be used more economically 

 in goods that are sold by bulk ; provided its gravity is lower. In 

 figuring the price of goods sold by bulk, it is always necessary to 

 have in mind, not the cost per pound, but the cost per cubic foot. 

 This, of course, involves a knowledge of the gravity, obviously 

 the apparent gravity and not the actual. 



Yours very truly, L. E. Weber. 



Boston India Rubber Laboratory, July 9, 1912. 



the united states tire company builds in boston. 



The L'nited States Tire Co. is going to erect a substantial 

 structure in Boston at the junction of Commonwealth avenue 

 and Beacon street. The company hopes to have this building 

 ready for occupancy by the beginning of the new year and in- 

 tends, at that time, to move into it from its present location on 

 Boylston street. 



The building, w^hich is to be of fireproof construction, will have 

 five stories. The manager's office will occupy the street floor, 

 along w'ith the general salesroom. The main offices will be on 

 the second floor, and the floors above will be devoted to stock. 

 The truck tire department is to be located in the basement, and 

 there also will be the service department of the branch. The 

 service department will be conducted entirely separate from the 

 sales department. The plans call for a driveway to the base- 

 ment for the convenience of ciistomers. This building will have 

 one of the most prominent locations in the newer automobile dis- 

 trict, facing the square, where Commonwealth and Brookline 

 avenues and Beacon street come together.
