The Canada 2c. brown registration is at this time mentioned frequently in the _Figaro_ and several other philatelic publications. As there seems to be considerable doubt as to the origin, and as I was in the main instrumental in introducing them to the philatelic public, I have decided to give the information I possess on this subject to them. About the beginning of January, 1887, I was shown a registered letter received from Miscou Light House Post Office in New Brunswick. It had a BROWN 2c. registration stamp on it--a clear unmistakable dark brown. I immediately wrote the postmaster there for information relative to them. He answered and said that he had 23 on hand. That he had originally received 50 from the P. O. Dept. at Ottawa, and that they were BROWN when he received them. This he stated positively. I then sent to him for them, but before my letter reached him he had used two of them so that I received only 21. Those stamps I showed to several philatelists, and could not get two to agree as to their origin. Some said the change in color was due to the gum, others to chemical changes, others again said it was due to the atmosphere from the salt water. Very few would allow a misprint. In the meantime Mr. F. C. Kaye also came across another registered letter with brown registration stamp. This time it was from the P. O. of New Ross in Lunenberg Co., N. S. From this office about 50 were obtained. The postmaster at this office was also positive as to having received them from the Dept. at Ottawa in brown. The same objections were raised to those as to the others, as to whether they were a genuine misprint or not. In this case the atmosphere of salt water was not the cause as New Ross is in the interior. If the gum was the cause of their changing color, it is peculiar that we do not get more of them. Changes by chemical means were also tried. The only thing which would turn the red of the genuine color to brown, was sulphuric acid mixed with water, and this did not give a good clear color, having a somewhat greyish shade in it. Those experiments have, in my opinion, confirmed their genuineness. And now as if to make assurances in regard to their genuineness more sure, we find a third post office with them. This was Beauly, in Antigonish Co., N. S. There were, however, only 6 received from there, the postmaster had the same story as the others, he had received them from the Dept. at Ottawa in a brown color. The Department at Ottawa was written to in regard to them, but as was to be expected, knew nothing of them whatsoever. No doubt if they had been seen they would not have been allowed to be issued to the public. Again we find some details given in _Mekeel's Weekly Stamp News_[199] under "Canadian Notes" which evidently refer to another lot:--
