But for this purpose I find it is sufficient to add a very small quantity of the outer peel to the extract a little before it is taken off the fire, and there will be all that is requisite to make it entirely equal to the freshest fruit. (b) _How to preserve berries and other fruits for long periods._ And it may be proper to acquaint them that most berries, and several fruits, when gathered two-thirds ripe on a dry day, while the sun shines, if put into earthen pots, or rather in dry bottles, well corked, and sealed up, so that no air or moisture can enter, will keep a long time, and at the end of a year, be as fresh as when new pulled. (c) _Method of preparing an antiscorbutic decoction from fir-tops, leaves, bark, etc._ When the Swedes carried on a war against the Muscovites, almost all the soldiers of their army were destroyed by the scurvy, having putrid gums, rigid tendons, etc. But a stop was put to the progress of this disease by the advice of Erbenius, the King's physician, with a simple decoction of fir-tops, by which the most deplorable cases were perfectly recovered, and the rest of the soldiers prevented from falling into it. I am inclined to believe by the description given by Cartier of the ameda tree, with a decoction of the bark and leaves of which his men were so speedily recovered, that it was the large swampy American spruce tree. A simple decoction of the tops, cones, leaves or even green bark and wood of these trees is an excellent antiscorbutic medicine; but it will, I am apt to think, become much more so when fermented, as in making spruce beer. By carrying a few bags of spruce or its extract to sea, this wholesome drink may be prepared at any time. But where it cannot be had the common fir-tops used for fuel in the ship should be first boiled in water, and the decoction afterwards fermented with molasses in the common method of making spruce beer; to which a small quantity of wormwood and horse-radish root (which it is easy to preserve fresh at sea) may be added. The juice of the cocoanut tree was experienced to be of very great benefit to several persons afflicted with the scurvy.
