The Oologist, referring to our illustration of Wilson's school-house, says:

"Grossart's Life of Wilson, 2 volumes, 8 vo. (Paisley, 1876) contains an engraving of Wilson's school-house, about which the editor states: "It is with very special pleasure I am enabled to give here an engraving (after a photograph) of the humble school-house within which Wilson, for many years, taught and dwelt. I have reason to believe that it has never before been engraved. It is now situated within the shadow of Philadelphia. - G.' Grossart may be right in his statement that the school-house had not previously been engraved. But Wilson certainly never 'dwelt' in his school-house, at least so far we have found no record of such fact.

" But we do find that at this time he boarded with a Mrs. Leach adjoining the ' Sorrel Horse Hotel,' a painting of which, and Mrs. Leach's cottage, by Alexander Wilson, is in our possession.

" In March, 1876, a picture of Wilson appeared in Scribner's Magazine, also an engraving of the school-house, which, with the present engraving, if correct, the ground has certainly been graded and many of the trees cut away since the days of Wilson. We have an impression that we have other engravings of Wilson's school-house, but at this time we know not where they are".

[The Oologist is correct in its supposition that Wilson boarded in the "Sorrel Horse Hotel," which was owned by Mr. Isaac Leech (not Leach), an uncle-in-law of the writer of this. The school-house was built on land belonging to a portion of the old Bartram estate, the land being given so long as the building should be used for school purposes. The new public school has of course rendered the little old school unnecessary. The school building stood too near the road to preserve. The filling in of the valley and widening required for city purposes, made its preservation impossible. Still we have no doubt if those who love the memory of Wilson had indicated any desire for its preservation, it could have been easily moved back. It is a misfortune that the world only comes to a knowledge of its true benefactors so long after they are gone. If anything remains of them then it is treasured; but too often all material traces are lost before the time of recognition comes.

[While on the subject we may note that few men did more for intelligent horticulture in America than did Bernard McMahon in his day. His house was a rendezvous for Pursh, Lyon, Nuttall, and many whose names stand boldly out in history. That also is now in the line of a city street, and will no doubt soon have to go. - Ed. G. M].
