Four years after the Cooper collection was sold for £3,000, Mr. Philbrick, to the deep regret of all his British colleagues, sold his general collection (not the Great Britain portion) to M. la Rénotière in Paris, for the then record price of £8,000. At his death, which occurred so recently as Christmas, 1910, it would have represented the comfortable fortune of, say, £50,000! It would be a shorter task to say what was _not_ in this truly wonderful collection than to attempt a list of its gems, for the absentees were almost _nil_. The best idea of the strength of this collection must be gathered from the valuable papers Philbrick contributed to _The Stamp Collector's Magazine_ and _The Philatelic Record_, chiefly under the pseudonyms "Damus petimusque vicissim," "An Amateur," and several "By the author of the 'Postage Stamps of British Guiana,'" and by his collaborated work with the late Mr. W. A. S. Westoby, "The Postage and Telegraph Stamps of Great Britain." Here I may fittingly place on record a souvenir I recently acquired of this collaboration and close friendship between these two most renowned of the students of stamps, whose work is a classic in the literature of Philately, and is still constantly referred to, being only in some respects superseded by later authorities. The letter itself amply justifies publication in entirety here, as it throws an interesting light on the philatelic evidence before the Joint Committee on Postage Stamps appointed by the Postmaster-General, the "confidential" report of which was printed in 1885 ("Bibl. Lindesiana," p. 159). "11, EARL'S AVENUE, FOLKESTONE, "_December 29th_. "MY DEAR PHILBRICK,-- "After seeing you on Saturday I wrote a letter to Mr. Jeffery saying that you had told me the substance of what passed, and that I most thoroughly endorsed what you had said about forgery. It was not the difficulty of forging a stamp which constituted their protection, so much as the difficulty of disposing of the stamps when forged.
