Gumbril senior occupied a tall, narrow-shouldered and rachitic house in a little obscure square not far from Paddington. There were five floors, and a basement with beetles, and nearly a hundred stairs, which shook when any one ran too rudely down them. It was a prematurely old and decaying house in a decaying quarter. The square in which it stood was steadily coming down in the world. The houses which a few years ago had all been occupied by respectable families, were now split up into squalid little maisonnettes, and from the neighbouring slums, which along with most other unpleasant things the old bourgeois families had been able to ignore, invading bands of children came to sport on the once sacred pavements. Mr. Gumbril was almost the last survivor of the old inhabitants. He liked his house, and he liked his square. Social decadence had not affected the fourteen plane trees which adorned its little garden, and the gambols of the dirty children did not disturb the starlings who came, evening by evening in summer-time, to roost in their branches. On fine evenings he used to sit out on his balcony waiting for the coming of the birds. And just at sunset, when the sky was most golden, there would be a twittering overhead, and the black, innumerable flocks of starlings would come sweeping across on the way from their daily haunts to their roosting-places, chosen so capriciously among the tree-planted squares and gardens of the city and so tenaciously retained, year after year, to the exclusion of every other place. Why his fourteen plane trees should have been chosen, Mr. Gumbril could never imagine. There were plenty of larger and more umbrageous gardens all round; but they remained birdless, while every evening, from the larger flocks, a faithful legion detached itself to settle clamorously among his trees. They sat and chattered till the sun went down and twilight was past, with intervals every now and then of silence that fell suddenly and inexplicably on all the birds at once, lasted through a few seconds of thrilling suspense, to end as suddenly and senselessly in an outburst of the same loud and simultaneous conversation.
