"Will this stuff keep any time?" inquired my wife, who came to see how we were getting on. "Or must all this great bagful be used at once? In that case we shall have to spend the whole of to-morrow in baking cakes." "Not at all," I replied; "once dry, the flour in barrels will keep fresh a long time. We shall use a great deal of this, however, as you shall see." "Do you think we might begin now, father?" said Fritz. "There does not seem the least moisture remaining." "Certainly," said I. "But I shall only make one cake to-day for an experiment; we must see how it agrees with Master Knips and the hens before we set up a bakehouse in regular style." I took out a couple of handfuls of flour for this purpose, and with a stick loosened and stirred the remainder, which I intended should be again pressed. While an iron plate, placed over a good fire, was getting hot, I mixed the meal with water and a little salt, kneaded it well, and forming a thickish cake, laid it on the hot plate, when one side presently becoming a nice yellow-brown color, it was turned and was quickly baked. It smelt so delicious that the boys quite envied the two hens and the monkey, who were selected as the subjects of this interesting experiment, and they silently watched them gobbling up the bits of cake I gave them, until Fritz turned to me, saying, "Suppose the cake is poisonous, what effect will it have on the creatures? Will they be stupefied, or will they suffer pain?" "That depends upon the nature of the poison. Some cause violent pain, as colchicum, hellebore, and aconite. Others produce stupefaction and paralysis, as opium, hemlock, and prussic acid; while others again, as strychnine, are followed by violent convulsions, or, as belladonna, by delirium. The effects of course vary according to the quantity taken, and such remedies should be applied as will best counteract the effect of each poison: emetics in any case, to remove as much as possible of the noxious substance, combined with oils and mucilaginous drinks to soothe and protect the stomach in case of irritants; stimulants, such as spirits, ammonia, or strong coffee to rouse from the stupor of the narcotics; and sedative drugs, which are perhaps in themselves poisons, to counteract the over stimulation of the nerves caused by the convulsant poisons. But now let us think no more of poisons; here is supper ready and we need not be afraid to eat roast penguin and potatoes." No sooner said than done; we left the fowls picking up the least crumb they could find of the questionable food, and assembled to enjoy our evening meal. The potatoes were, as usual, excellent, the penguin was really not so bad as I expected, although fishy in taste and very tough. Next morning every one expressed the tenderest concern as to the health of Knips and the hens; and lively pleasure was in every countenance when Jack, who ran first to make the visit inquiry, brought news of their perfect good health and spirits.
