A German publication states that a new method of keeping potatoes and preventing sprouting consists in placing them on a layer of coke. Dr bonnier, of Brunswick, who has published the method, is of opinion that the- improved ventilation by means of coko is not alono responsible for the result, but believes that it is due to the oxidation of the coke, which, however, is a very slow one Coke always contains sulphur, and it is very possible that the minute quantities of oxidised carbon and sulphur which result from the oxidation, mixing with the air and penetrating amomT the potatoes, are sufficient to greatly retard sprouting. Potatoes so treated are said to keep in good condition until the following: midsummer.
