the woodland drives and paths. Luncheon tables and benches have been provided in pleasant nooks for basket picnic parties. A stairway with frequent landings has been constructed on the left bank of the river by the Upper Fall. A bridge with masonry abutments has been built near the Cascade. A substantial gallery has been constructed along the face of the cliff opposite the Upper Fall. A gravel path has been made along the left bank of the river from the Middle Fall to the Mineral Spring. A broad walk has been made along the high bank of the gorge between the Middle and the Lower Falls. The walks about the Lower Falls have been extended. The picnic grounds at the Lower Falls have been improved by the erection of a substantial shelter or pavilion for refuge in case of storm. The driveway from the north entrance of the park to the Lower Falls has been improved. The grove, picnic ground and playgrounds on the bluff overlooking the Glen Iris residence grounds have been developed. And signboards have been erected for the guidance of visitors and their information concerning certain notable places, such as the point from which the artist Thomas Cole painted his famous view of the gorge below the Middle Fall, and the point at the Lower Falls where the artist James M. Hart painted another view.

A fire-proof library building, a statue of Mary Jemison, White Woman of the Genesee," and other liberal improvements are contemplated by Mr. Letchworth.

In the spring of 1907, the American Museum of Natural History, through the generosity of the late Mr. Morris K. Jesup, President, and the kindly co-operation of Dr. H. C. Bumpus, Director, donated to the Glen Iris Museum two life-sized busts representing an Iroquois man and woman.

In June and July the Secretary of this Society and Prof. Amadeus W. Grabau of Columbia University made a preliminary survey of the three falls and set a number of copper bolts to serve *Mary Jemison's grave is shown in the accompanying illustration.

as bases for measurement of the recession of the falls. At the same time Prof. Grabau prosecuted his geological research of the region, with valuable results which were laid before the Geological Section of the New York Academy of Sciences at its meeting in the American Museum of Natural History, December 2, 1907, and before the Geological Society of America at its annual meeting in Albuquerque, N. M., December 30-31, 1907.

In September, under the guidance of Mr. Letchworth, the Secretary made a new map of the Park, laying out upon it the lines of certain new drives designed to give greater accessibility to points of vantage, and certain areas designed for reforestation.

In October, through the kind co-operation of Dr. Nathaniel L. Britton, Director of the New York Botanical Garden, Mr. George V. Nash, Head-Gardener for that institution, was delegated to visit Letchworth Park and designate a number of the most interesting species of trees for labeling with their botanical and popular names. Later, lead labels, specially worded but after the general design used in the New York Botanical Garden, were made for Mr. Letchworth at cost at the latter institution and are ready for affixing. A still larger use of these labels is contemplated for the increased educational usefulness of the Park.

Speaking of his visit to Letchworth Park, Mr. Nash says:

*

The object of my visit to this park was to name and have properly labeled the trees in the vicinity of the roads and paths, which Mr. Letchworth has constructed and is constructing through this tract, that the public may have easy access to all of its beauties. One is at once struck here by the purity of the vegetation. By this I mean the almost entire absence of plants not native to the tract. Even in the immediate neighborhood of the house, where the open lawns would permit of such treatment, but few extraneous species are to be found. Such plants are, however, represented by the horse-chestnut (sculus Hippocastanum), of Greece, the sweet or yellow buckeye (Esculus octandra), of the southIn Torreya," vol. 7, No. 11, November, 1907.

eastern United States, and the fetid or Ohio buckeye (Esculus glabra), of the central United States. Others of this nature are the sweet gum (Liquidambar Styraciflua), the Norway maple (Acer platanoides), of Europe, the maiden-hair tree (Ginkgo biloba), of China, the purple form of the European beech (Fagus sylvatica purpurea), the Norway spruce (Picea excelsa), of Europe, in some noble specimens, and the Colorado spruce (Picea Parryana). It is plain on all sides that every attempt has been made to keep things as nature made them. The arboreal vegetation is well represented, and in one region down near the Lower Fall, inaccessible to the lumberman on account of the precipitous bluff on one side and the raging waters of the river on the other, are some large trees, perhaps representing the original growth. I had a most enjoyable time for two days going over this tract. Of course in that limited period it was not possible to make an exhaustive study of the trees, my operations being confined to the vicinity of paths, but here a large proportion of the species must be represented.

Among the conifers the most common tree is the white pine (Pinus Strobus). This grows in great quantities, springing up readily on all unoccupied lands. Occasionally, where the destroying ax of the lumberman did not do its deadly work before Mr. Letchworth acquired possession of the land, large specimens of this tree are to be found. The next conifer in point of frequency is also a pine (Pinus resinosa), the Canadian, Norway, or red pine. This also has attained a great size in places, especially along the path which skirts the north shore of the river on the way to the Lower Fall. The red cedar (Juniperus virginiana) occurs sparingly. The hemlock (Tsuga canadensis) is also quite common, vying in frequency with the Canadian pine. The tulip-tree (Liriodendron Tulipifera) is quite conspicuous in places with its shaft-like columnar trunks, and the American beech (Fagus grandifolia) added a touch of gray to the forest. The American elm (Ulmus americana), the chestnut (Castanea dentata) and the American linden or basswood (Tilia americana), are of frequent occurrence. The dreaded chestnut disease, which is causing such havoc to these trees in the vicinity of New York city, does not appear as yet to have reached this neighborhood. A single tree
