The house, of the usual type of those days, with a hall passing through the centre and rooms on either side, was built of rubble-stone by Roland Evans in 1762, and in 1774 was sold to Admiral Audubon, who in the year following built an addition, also of rubble-stone. This addition is lower than the main house, which consists of two full stories and an attic with dormer windows, where, it is said, Audubon kept his collections. The same Franklin stove is in the parlor which stood there giving out its warmth and cheer when the young man came in from the hunting and skating expeditions on which he loved to dwell. The dense woods which once covered the ground are largely cut down, but sufficient forest growth remains to give the needed shade and beauty; the hemlocks in particular are noticeable, so large and of such perfect form. Going down a foot-path to Perkiomen Creek, a few steps lead to the old mill which gave the place its name. Built of stone and shaded by cottonwood trees, the stream rushing past as in days long gone, the mill-wheel still revolves, though little work is done there now. When I saw Mill Grove[21] the spring flowers were abundant; the soft, pale blossom of the May-apple (_Podophyllum peltatum_) held its head above the blue of many violets, the fingers of the potentilla with their yellow stars crept in and out among the tangled grass and early undergrowth; the trilliums, both red and white, were in profusion; in the shade the wood anemones, with their shell pink cups grew everywhere, while in damp spots by the brook yet remained a few adder's-tongues, and under the hemlocks in the clefts of the rocks the delicate foliage of the Dutchmen's breeches (_Dicentra cucullaria_) with a few late blossoms; all these and many more which I do not now recall, Audubon has pictured with the birds found in the same regions, as his imperishable tribute to the home he loved--Mill-Grove Farm on the Perkiomen Creek.
