According- to J. E. Kehl, United States consul at Stettin, (xormany, 

 the manufacture of peat briquettes in that country is likely to become 

 an industry of some importance. The material fresh from the moor 

 is cut and ground quite Hnely by machiiuu-y, dried by steam, and 

 pressed into the desired form. The matcn-ial thus prepared is said to 

 be clean to handle, giyes a good heat, and burns satisfactorily in ))oth 

 stoyes and open grates. The peat bricpiettes retail at the rate of 8 for 

 a cent, American money.' 



From a study made by Drs. J. W. Dawson and B. J. Harrison 

 some years ago^ it was concluded that the peat deposits of Prince 

 Edward Island were capable of economic utilization. Three deposits 

 were referred to, the possibilities of which were giyen as below: 



Lenox Island bog, at $4 a ton, 20,000 tons, value $80, 000 



Squirrel Creek bog, at $4 a ton, 500,000 tons, value 2, 000, 000 



Black Bank bog, at $4 a ton, 1,777,248 tons, value 7, 108, 992 



Total 9, 189, 992 



The following analyses of peats are giyen by this authority: 



Below are giyen the results of analyses of I, peat from bog of 

 Allan. Ireland; II, a "muck", from Maine, United States; and III, 

 Commander Islands in Behring Sea (Specimen No. 59320, U.S.N.M.): 



Lignite or brown coal. — This name is giyen to a brownish -black 

 variety of coal characterized by a brilliant luster, conchoidal fracture, 

 and brown streak. Such contain from 55 to 65 per cent of carbon and 

 burn easily, with a smok}^ flame, but are inferior to the true coals for 

 heating purposes. They are also objectionable on account of the soot 

 they create, and their rapid disintegration and general deterioration
