Edmund Barrett.] INTRODUCTION It is difficult to understand how a house whose history is closely connected to the well-known Mason family has existed, practically without notice or mention, for one hundred and fifty years. This fact is all the more puzzling when the structure is as architecturally important as "Huntley." Several possible explanations come to mind: * Though near a major highway, the house is isolated on its hillside site. * Because the structure has been somewhat altered, close inspection is necessary before its architectural merits can be fully recognized. * The house was a country or secondary home for a member of the Mason family who, though important in his own right, was overshadowed by his more illustrious father, Thomson Mason of "Hollin Hall", and by his grandfather, George Mason IV of "Gunston Hall." * No one has written in detail about the house before and there is little secondary material available concerning it. Kate Mason Rowland's _Life of George Mason_, published in 1892,[1] gives one of the few references to Huntley found by the author in secondary sources. In an appendix titled "Land described in George Mason's will, and now owned by his descendent's," she notes: It was incorrectly stated in one of the earlier volumes that "Lexington" was the only one of the Mason places in Virginia now in the family. The writer had overlooked "Okeley" in Fairfax County, about six miles from Alexandria. The farms of "Okeley" and "Huntley" were both parts of the estate bequeathed by George Mason to his son Thomson Mason of "Hollin Hall." A double ditch[50] is still to be seen on the southern border of these two places, extending several miles from East to West, with a broad space about thirty feet wide separating the two ditches. These mark the line between the lands of George Mason and George Washington, as they were in the lives of those gentlemen. In General Washington's will he refers "to the back line or outer boundary of the tract between Thomson Mason and myself ... now double ditching with a post-and-rail fence thereon," etc. And he mentions in another place "the new double ditch" in connection with the boundary line between "Mt. Vernon" and the Mason property. In adding to his estate he had purchased land at one time from George Mason. And among the Washington papers preserved in the Lewis and Washington families, and recently sold to autograph collectors, are three letters of George Mason, on the subject of the bounds between the Washington and Mason plantations, one written in 1768, the others in 1769. Washington adds a memorandum to the former, saying that "the lines
