Pedicularis sylvatica, Polygala vulgaris, Viola tricolor & some species of Trifolium, I have watched the flowers day after day without seeing a bee at work, and then suddenly all the flowers where repeatedly visited by many bees. Now how did so many bees discover at once that the flowers were secreting nectar? I presume that it must have been by their odour, and that as soon as a few bees began to suck the flowers others of the same & of different species observed the fact & profited by it. We shall presently see when we come to the boring of the corolla that bees are fully capable of profiting by the a work performed of others bees. Memory also comes into play for as already remarked bees know the position of each clump of flowers in the garden; thus I have repeatedly seen them parsing round a corner, but otherwise in as straight a line as was possible, from one plant to another a distant one of Fraxinella & of a tall Linaria to another & distant one; although that was not in sight of the other owing to the inter
