This time, however, you fill them not with manure but with quartz or silica or even orthorclase or felspar, ground to a fine mealy powder, of which you make a mush, say of the consistency of a very thin dough. With this you fill the horn. And now, instead of letting it “hibernate,” you let the horn spend the summer in the earth and in the late autumn dig it out and keep its contents till the following spring.
