=Forest and Animal Life of the Catskills.=--The interior region of the Catskill Mountains surrounding Kaaterskill Junction is assigned, by Dr. E. A. Means in a paper of the United States National Museum, to the Canadian faunal region, with a slight mixture of the Alleghanian in the farming lands on the banks of Schoharie Creek. A few mammals of the Upper Austral zones, however, such as the New England cottontail, the deer mouse, and the gray fox, appear to have extended their ranges into the locality by following up the clearings. Though the region is now again well wooded, only the barest tags and remnants yet remain of the splendid forests that once covered the area. All is second growth except in the rockiest gulches, whence the lumber can not be extracted, and about the rocky summits of a few mountains of the East Jewett ranges. While the original forests seem to have been of conifers, the woods are now very thoroughly mixed, and the succession of trees according to altitudes, with its strongly marked division lines, is no longer seen. Specimens of fifty-eight species of trees and shrubs have been collected and placed in the National Museum. Only ten species of mollusks, one crustacean (the common crawfish), probably a dozen fishes (the author identifies eight and mentions others), eight batrachians, two snakes, and a turtle have been found. Of mammals, thirty-five species are described as known to occur at the present time, and eight as of doubtful occurrence now. =Geology of Block Island.=--In a study of the geology and natural history of Block Island, of which Arthur Hollick gives a summary in the Annals of the New York Academy of Sciences, the most important problem was whether the Amboy clay series was represented in the island. Of fifteen species of fossil leaves and fruit capable of identification, represented by about twenty-five specimens, at least nine were typical of the Amboy flora. Observations on dip and strike of strata tended to emphasize the fact of contortion of glacial action, the dip in all cases being toward the north, indicating that the strata had been pushed southward in a series of overthrust folds by the advancing ice front. The flora may be divided physiographically into that of the hills, the peat bogs and pond holes, the salt marshes, the sand dunes, and the salt water. Trees are rare, and such vegetation as is dependent on forestal conditions is absent. The bulk of the surface is that of a typical morainal region, with rounded hills and corresponding depressions, many of the depressions being occupied by swamps or ponds, often without any visible outlet. Running streams are few and insignificant, and permanent springs occur only in a limited number of localities. The soil is bowlder till and gravel, with sand in the dunes and beaches, and there are no outcrops of rock. The flora is morainal in its general character, except in the peat bogs and on the limited sand dunes and sea-beach areas, and has its
