During this part of my journey particularly, the need of a small coal- oil stove was felt, as the usual custom of making a camp-fire could not be followed for many days on the upper Ohio River. The rains had wet the fire-wood, which in a settled and cultivated country is found only in small quantities on the banks of the stream. The driftwood thrown up by the river was almost saturated with water, and the damp, wild trees of the swamp afforded only green wood. In a less settled country, or where there is an old forest growth, as along the lower Ohio and upon the banks of the Mississippi, fallen trees, with resinous, dry hearts, can be found; and even during a heavy fall of rain a skilful use of the axe will bring out these ancient interiors to cheer the voyager's heart by affording him excellent fuel for his camp-fire. The recently perfected coal-oil stove does not give out disagreeable odors when the petroleum used is refined, like that known in the market as Pratt's Astral Oil. This brand of oil does not contain naphtha, the existence of which in the partially refined oils is the cause of so many dangerous explosions of kerosene lamps. Recent experiences with coal-oil burners lead me to adopt, for camp use, the No.0 single-wick stove of the "Florence Machine Co.," whose excellent wares attracted so much attention at the Centennial Exhibition in Philadelphia. The No. 0 Florence stove will sustain the weight of one hundred and fifty pounds, and is one of the few absolutely safe oil stoves, with perfect combustion, and no unpleasant odor or gas. This statement presupposes that the wicks are wiped along the burnt edges after being used, and that a certain degree of cleanliness is observed in the care of the oil cistern. I do not stand alone in my appreciation of this faithful little stove, for the company sold forty thousand of them in one year. In Johnson's Universal Cyclopdia, Dr. L. P. Brockett, of Brooklyn, N.Y., expresses himself in the most enthusiastic terms in regard to this stove. He says: "For summer use it will be a great boon to the thousands of women whose lives have been made bitter and wretched by confinement in close and intensely heated kitchens; in many cases it will give health for disease, strength for weakness, cheerfulness for depression, and profound thankfulness in place of gloom and despair." Boatmen and canoeists should never travel without one of these indispensable comforts. Alcohol stoves are small, and the fuel used too expensive, as well as difficult to obtain, while good coal-oil can now be had even on the borders of the remote wilderness. The economy of its use is wonderful. A heat sufficient to boil a gallon of water in thirty minutes can be sustained for ten hours at the cost of three cents.
