true, under some circumstances—viz. If the same pocas ‘of 
Schuylkill coal: (which is are about 8 per cent. lighter 
than Lehigh) should be submitted to the same powerful 
draught, or blast, as the Lehigh, it would consume faster 
but I be-lieve an equal weight, and with a properly graduated 
draught, to produce the best combustion, that the Schuylkillcoal 
' will be founda little superior to any other of the psig seecssan 
coals yet discovered. 
The grates for the Schuylkill coal are of various: construc 
tion, but generally with vertical bars, although many persons | 
urn the Schuylkill coal in the old Liverpool grates, with 
some newae nap sang in the draught. The best kindling is

As to future supplies rae the mines, there is but one Kimits 
‘ng cause—and that is the capacity of the canal to float it to 
Philadelphia. It is intended to bring 25,000 tons next year, 
which will be equal to 100 tons per “day, ‘for eight months. 
It is expected that ubtieaitely; four times that quantity will be 
ught to market annually. 
It is stated that 8,800 tons of the Lehigh coal had been 
received in New York during the present season up to Janu- .

They are both so valuable, that there need be no competition 
‘between them, and the anthracite of W Mhosherre ix, I pre-

Tt appears to me that the Schuylkill coal isi: more 
readily than the Lehigh, and begins to warm the apartment 
sooner, but with the same draught of air, it does not endure’ 
so long. I see no great difference in the degree of heat 
which is finally produced, and by checking the draght after
