For contrast, a place on the coast just opposite, as it were, and almost within view, at the same time of year seemed to have no bees. A great field of clover in flower was silent; there was no hum, nor glistening of wings. Butterflies rarely came along. Swallows were not common. In the rich loam it was curious to note mussel-shells, quite recent, in good preservation, and a geologist might wonder at the layers of them in such an earth; the farmer would smile, and say the mussels were carted there for manure. Another place, again, in the same county is full of rooks, and the arum is green on the banks. These items in a small area show how different places are, and if you move from locality to locality everything you have read about is by degrees seen in reality. In an old book, the History of Northampton, which I chanced to look at, among other curiosities, the author a hundred years ago mentioned a substance called star shot, which appeared in the meadows overnight, and seemed to have dropped from the sky. This I had not then seen, but many years afterwards came suddenly, by a copse, on a quantity of jelly-like substance with a most unpleasant aspect, but which did not in any other way offend the senses. It had shot up in the night, and was gone next day. It is a fungus unnoticed till it suddenly swells; I suppose this was the old chronicler's star shot. Nor do I think it too small a thing that the common snail makes a straight track over everything; if he comes to the wall of a house he goes straight up without the smallest hesitation, and explores a good height before he comes down again; if he finds a loaf of bread in the cellar he never thinks of going round it, but travels in a Roman road up and over. So do the armies of ants in warmer climates, and this proceeding in an invariable line irrespective of obstacles seems to be peculiar to many creatures, and is the reason why such 'plagues' were and are so dreaded. Nothing could divert the straight march of the locusts; nothing could divert the course of the millions of butterflies that sometimes cross the Channel and arrive here from the Continent.
