FOR STEAM. 



Detroit, January 16, 1854. 



R. R. Lansing — Sir: — The six tons of Michigan coal you sent us 

 for testing its power to raise steam, has been tried on board the Pearl, 

 Captain Goodsell, first on a trip to Maiden — Mr. Smith, our Chief En- 

 gineer, being on board — and next on a trip to Port Huron. 



Their report to us is that the coal burned freely, emitting a great 

 deal of flame, and raising steam rapidly ; was reduced to ashes without 

 exhibiting any evidence of sulphur, or leaving any slag or clinker, or 

 making any impression on the grates of the furnaces, which, after the 

 experiment, were left as free from any adhesive matter as if wood had 

 been burned. Wood had uniformly been burned in the furnaces, and 

 therefore any injury to the grates could be readily detected. 



Respectfully yours, E. B. Ward. 



FOR ILLUMINATING GAS. 



BiDDLE House, Detroit, Januaiy 16, 1854. 

 Col. R. R. Lansing — Dear Sir: — Some time since you favored 

 me with a sample of Michigan coal, for the purpose of testing its gase- 

 ous qualities. My gas apparatus being on a small scale, is perhaps as 

 well calculated for making such a test as any other, because an imme- 

 diate result can be veiy readily produced. My decided opinion is, that 

 your coal yields as much gas as any other domestic coal used for that 

 purpose, and its luminous qualities certainly exceed any other gas man- 

 ufactwed by us. Respectfully, &c., Orville B. Dibble. 



FOR COKE. 



Detroit, January 23, 1854. 

 The circumstances in which I have been placed, during many years 

 of my hfe, have been such as to warrant me in giving an opinion with 

 regard to coke. I have seen some hundreds, or I might say soioe
