* * * * * Perfection Lemon-Squeezer. Price 35 cents; for 40 cents in new subscriptions. Postage 6 cents. [Illustration] Not a squeezer at all, but better. Press half a lemon down over the burr and turn it round with the hand. The burr cuts the pulp, dislodges the juice and saves it all without squeezing the bitter oil of lemon out of the rind. No seeds, no waste, no spattering. * * * * * Cold stove-door Knob. Price 6 cents; for 8 cents in new subscriptions. [Illustration] Wood handle; hangs on the knob, saves burning the fingers. * * * * * Dust-pan. Price 25 cents; for 35 cents in new subscriptions. Postage 12 cents. [Illustration] [Illustration] Japanned-steel; propped up behind in position to use so that one need not stoop to hold it by hand—a touch with the foot is enough. * * * * * Kerosene-brick for burning kerosene in any cook-stove, heater or open fire-place, as kindler or fuel. Porous fire brick. [Illustration] We do not know (at the time of writing) its limit of value, having only just now got it. It is safe—no doubt of that. It is the best kindler ever discovered—no doubt of that. But to what extent it is going to be used for summer fuel and fuel for transient occasions of all sorts we do not know. It is a new thing of very great importance everywhere. We therefore state what we know of it carefully. The reason why it does not explode is that the oil is fast in the pores of the brick and can’t get out, except as it is slowly driven out by the fire. Kerosene lamps are dangerous; but you are careful with them. There is no possible way in which the kerosene-brick can explode. The only harm that can come of it is through keeping a larger supply of kerosene for fuel then you would keep for light. The answer to that is that a barrel is no worse than a pint. Either is enough to blow a house into kindling-wood. The reason why it is the best kindler is that it is the cheapest—in other respects it is not much better than pitch-pine. Tradesmen are likely to overstate the cheapness of it; but it is very cheap—how cheap depends, of course, on the cost of your kerosene; and that is so different in different parts of the country that we cannot give the cost of using the kerosene-brick. It saves its cost in wood perhaps ten times over. It makes smoke and soot; but they go up chimney. The first cost of the kerosene-brick is as follows:[A] No. 1.
