Fort William, John Green, 



20th January, 1778. Commissary of Stores, 



A report of the trial made between the British sea-coal and the country 

 coal furnished by Messrs. Sumner, Heatly, and Redfearne, Fort 

 William^ the \Zth January, 1778. 



Country Coal, one maund. 



Two welding heats were given to fifteen seers of iron, one foot long, 

 two and half inches broad, one and half inch thick. The first heat 

 required thirty-seven minutes, the second with the same fire and the 

 remainder of the coals was sixteen minutes. 



N.B. — It burns away very quick, the refuse is nothing but clinker 

 slate and dirt, without the least remains of cinders or clean ashes, and 

 it wastes the iron very much. Yet these coals are far preferable to 

 those sent for a former trial. 



British Sea Coal, one maund. 



Two welding heats were given to fifteen seers of iron of the above 

 dimensions. The first heat required thirty minutes, the second heat five 

 minutes, with a quantity of coals remaining sufficient to have given two 

 more heats. 



N.B.— It is plain from this trial between the two sorts of coals, that 

 with one maund of the British, the same work may be performed that 

 can be done with two maunds of the country, in much less time, and 

 with not near so great a waste of iron. 



John Green, 

 Commissary of Stores. 



The Government resolution in consequence of the report, closes the 

 official correspondence of this period. 



Ordered, — That the Military Store-keeper be directed to return the 

 coal to the proprietors ; but that they be informed, the Board will 

 give them all reasonable encouragement in the prosecution of their
