A series of experiments have been made at the Com- 
mercial Gas Works, London, on condensed peat, the results 
of which are given below :—

The following, from a tabulated statement giving details of 
the various peat enterprises actually now working, will afford 
some interesting information on peat manufacture :—

From the foregoing it will be seen that peat fuel possesses 
a calorific power of five-sixths of coal, and can be produced 
in Canada and the United States at from 6s. 6d. to gs. per 
ton, where wages for labour are not lower than 7s. per day. 
The Peat Coal and Charcoal Company make a show of 
peat in all its stages, from the time it is taken from the bog 
to the time it is compressed and carved, for they have some 
pieces which have been cut into flowers and fruit, till it 
looks like carved ebony. This Company has bought the 
patent rights of M. Challeton de Brughat ; his process con- 
sists in making peat coal having nearly the same density as 
pit coal, and also he claims to have invented a better
