Schuylkill mines were worked for that purpose, in that year 

 about 6,500 tons of coal including Lehigh were brought to 

 market, some of whieh reached the city of New- York. The 

 mining operations for 1851, will exceed 3,000,000 tons. 



With the view of showing how and in what way the doings 

 and interests of the subscriber have been identified with the 

 coal mines of Pennsylvania, and the introduction of their coal 

 into use, particularly for the mass, the many he refers to 

 the following extract from a deposition made by himself 

 in the year 1847, in certain matters then pending before 

 the Hon. Secretary of State of the United States. And also 

 to the report from the examiner and commissioner of patents, 

 confirmed by the Hon. James Buchanan, to the effect that' the 

 invention of the subscriber produced a distinct era in fuel sa.- 

 ving. 



City and County of New- York, ss : 



Jordan L. Mott, applicant &c., being duly sworn, doth depose 

 and say that soon after the anthracite coal was brought to the 

 city of New-York, he commenced a series of experiments for the 

 purpose of devising some mode by which it might be used for 

 domestic purposes ; the apparatus then eojployed for burning 

 bituminous coal or wood not being adapted to this new fuel ; 

 that his first experiments were with the large sized coal, which 

 he soon abandoned and confined them to the small sized nut 

 coal, which was accumulating in large quantities in the yards, 

 and at the mines, was but little or no value, in most cases given 

 away. 



To contrive an apparatus in which the poor could use this seem- 

 inirly worthless coal was the chief object of this deponenVs experi- 

 ments, which he continued with varied success for the period of 

 five or six years, during which time he tried almost every con- 

 ceivable form of fire-place or grate. 



One serious objection to the use of large coal was the great 

 length of time required to make an availiblo fire. In the win- 

 ter of 1829, this deponent contrived a stove in wliich he could 

 make a fire with small coal in from five to ten minutes, using a« 

 kindling wood a small white wood segar box.
