THE CHESTER EMEEY BED. 133 



The quantity of manufactured emery at present annually consumed in the 

 United States is over 1,000 tons, and the consumption is rapidly on the increase. This 

 supply has hitherto been derived in part from London and partly from Alden's 

 manufactory at Ashland, near Franiinghain, Massachusetts, which establishment has 

 imported the crude stone direct from Smyrna, though it is now beginning to derive its 

 material from Chester. 



The estimation in which the American product is held is sullicently vouched for 

 in the following certificates, coming as they do from sources of the highest respecta- 

 bility. The letters are addressed to J. B. Taft, esq., of Boston, who is trustee for the 

 parties in interest to the property :

 Dear Sir: The samples of emery sent here for trial have been tested and decided to be auper- 

 excellent. The test has been made without the slightest knowledge of its character by either Jlr. 

 Chamberlain or the men. 



The Nos. 46 and 70 are not of the right grade, but the evenness of all the numbers and their 

 catting qualities can not be equaled by any Turkish or American emery. 

 Yours, truly, 



(Signed) E. S. Allin, M. A.

Boston, Massachusetts, December 1, 1S64. 

 We are very much pleased with the emery you left with us to try. We find it far superior to 

 anything we have heretofore used. We have bought the best that we could possibly fiud for years, 

 without regard to price, and we find by actual experiment that yours will do ono-third more work 

 than the best London emery. We have made a very careful experiment, and can give a more partic- 

 ular report if necessary. If you can supply us with the fine grades to compare with the samples left, 

 you can have all our orders as soon as wo use what stock we have on hand. 

 Very respectfully,

 Dear Sir : The two packages of emery, as samples, Nos. 46 and 70, were received and tried— the 

 46 on a lead wheel for cutting out grooves of blades and the 70 on a leather-covered wbeel for shaping 

 the Large grooves of saber blades. Either test requires good emery to do the work successfully. Wo 

 had not the means of making a comparative test, but the best thing I can say for it is that the work- 

 men would use no other kind if they could have emery like the samijle. This is of the very best (quality 

 we have had an opportunity to use. 



Yours, very truly, (Signed) ,Ias. T. Ames.

Milling Shop, April 25, 1S65. 



Sir: The following is a report on the relative qualities of American and English emery. No. 70, 

 as tested in this department. We have giveu it three difterent trials. The number of wheels set 

 with emery at each trial was 12, 6 with American and 6 with English. The wheels used for the first 

 trial were reversed for second trial, those being set with English emery in second trial that were used 

 with American in first trial, and vice versa. 



You will please notice the work as performed by dLiferent men with the same emery.
