In the evening I was amazed by what I saw. The toiling pair had been joined by about a dozen other martins, all bearing beakfuls of mud and grass to the precipitous site. In regular order came mud, quickly moulded and kneaded into place, then came a broken straw, a rootlet, or a twitch of grass. There was just time to place this in position before another bird would arrive. A sweet soft trickle of eagerness fell continually from just above my window. The next morning succour was still availing, and quickly the nest grew. We discussed this in the village, but even the oldest granfer had never heard tell of such a thing before. Toilers in the harvest fields (the “unimaginative labourers”) paused and regarded. They were interested, and many pondered the problem with me. “League o’ Nations,” grinned one. “There is much friendship among birds,” I said. “Aiy, aiy!” agreed another, and told me in the soft melodious burr of the west country how, in his garden that spring, a robin had fed a nest of hedge-sparrows. The nest was finished in three days. The lining of feathers was a speedy business, for I scattered a handful on the ground beneath, wishing to give my small aid. I am sure the pair were grateful, for on the fourth day, when I inspected from a ladder, the first egg was laid and the mother was not alarmed by my intrusion. This intensive construction is not usual. It is not instinctive. It is the result of reason and decency of life in their colonies. Rooks, being amoral, would not help one another. Martins live together in trust and decency. Who, hearing their song (jumbled though it may be), can doubt this. “League of Nations,” a simple man had said to me. I wondered if the hopes of Richard Jefferies will ever be fulfilled. Are not the eave-swallows wiser than us? Sometimes I think so. SPORTSMEN OF THE RUBBISH-HEAPS An old, faded notice board, bearing the legend that trespassers will be prosecuted, leans at a low angle in the hedge; newer and larger boards announce that the land is “admirable for building purposes” and for sale. A gate guards a gap in the hedge, over which bold boys swarm on Saturdays and Sundays when no policeman is in sight. This preserve, as the crow flies, is about eight miles from London Bridge in a south-easterly direction. It is known to dustmen, who dump their loads upon its once-green fields, and it is also known to certain cockney sportsmen.
