THIS book, begun many years ago, was laid aside under the stress of other work, which did not, however, hinder the sedulous amassing of notes during my long and continuous residence in Paris. The appearance of the Marquis de Rochegude’s exhaustive work, on somewhat the same lines in a more extensive compass, took me by surprise, and I thought for a moment that it would render my book superfluous. The vast concourse of English-speaking people brought hither by the great war, people keen to learn the history of the beautiful old buildings they find here on every side, made me understand that an English book of relatively small compass was needed, and I set to work to finish the volume planned and begun so long ago.
I had made the personal acquaintance and consequent notes of most of the ancient “Stones of Paris” before looking up published notes concerning them. When such notes were looked up, I can only say their sources were far too numerous and too scattered to be recorded here. I must beg every one who may have published anything worth while on Old Paris to receive my thanks, for I have doubtless read their writings with interest and benefit. But I must offer special thanks to M. de Rochegude, for—writing under pressure to get the book ready for press—his work as a reference book, while pursuing my own investigations, has been invaluable.
