The Lester and Halstead artificial fuel is composed of 60 per cent of peat, about 20 per cent of anthmcite dust, 10 percent coal-tar, 5 per cent asphaltum, but varying in proportionfor different purposes, whether metallurgical, domestic, or oth-er. The peat, dug in the usual manner, is laid in the air todry; and when dry enough to be mixed with the other mate-rials into an amalgam, it is put into a press, and with one Next day it is ready for use.
