COLLECTING AND CURATING FRUITS AND SEEDS. 49 for the tiny seeds and picking them out with the forceps, one by one, from a very much more bulky collection of grit and dirt, from which they are indistinguishable without the aid of a lens or powerful hand glass. As a matter of fact a very little material is enough, and my advice is to harvest that little as exclusively and as cleanly as possible. A word must be said about collecting seeds that are shot away by the parent plant. My own plan is to put a few sprays bearing nearly ripe fruits into a paper bag, in which they can be left in a dry place or exposed to sunshine, and then the first— instance dispersal will take place in the fulness of time. Few people, who have not tried, would believe how difficult it is to collect half a dozen seeds even from so large a plant as Geranium pratense without some help in catching them as they are shot off. There are, of course, more ways of collecting than from the parent. I have already mentioned animals, alive and dead, as well as dead leaves ; there are also, among other things, the pellets of birds, while the margin of a stream or of a sheet of water will often provide specimens which could not otherwise be secured without a boat or a wetting. All such methods, however, have the drawback that they involve naming the seeds without knowing the plants that bore them, and it is sometimes very difficult to be sure of the identity when there is no correctly named material for reference and comparison. I do not put into my own collection any seed so acquired which I cannot match in detail with others taken from a known parent. A wrong name must be avoided at all costs ; rather than make a mistake it is far better to call a seed of uncertain identity "Oenanthe," for ex- ample, or even "Umbelliferae," or, to be quite frank and label it "incog." It is, however, always interesting to sow such seeds in order to get the desired information, and so acquire incidentally some knowledge of the seedling and of the juvenile stages of the plants. Identification can often be helped by examining the embryo and endosperm, if there is any, but seeds so dissected should not be admitted to the collection, because such nutritious things as exposed endosperm are certain to be attacked by fungi and mites. I do not, however, wish to be misunderstood ; the wind dispersal of the Samphire cannot be appreciated without cutting into the pericarp and seeing the inter-cellular spaces,
