followed and the quarries reached in an hour from Belleville. Here again are met the sandstones and shales, besides another and larger fault, and many interesting features of the sandstone and its quarrying may be examined. The railroad station having been regained, Paterson is the next point of interest. The first thing noticeable in approaching the city are the quarries in the side of the hills to the south, and these may be visited the first; they are but a short distance southeast of the station. Here the sandstone will be found in contact with the trap above and the layers of basalt, trap, tufa, sandstone, shales and conglomerates are exposed. Regaining the nearest railroad track (the Boonton branch of the D., L. & W.R.R.), this is followed for some distance west, when the various strata can be examined in the cut of the railroad and a fault of nearly sixty feet in the trap; this is noticed as a depression in the face of the cliff, and it may be seen by the superposition of the layers of trap and basalt. Where the fault occurs a short distance further west, there is another smaller fault. A visit to the Great Falls of the Passaic is a very pleasurable diversion at this point, and these are about a half mile north of this locality. Here the arrangement of the trap and sandstones can be again profitably studied, and the mineralogical localities which I have described in a former one of these articles[2] examined, not omitting the one at West Paterson, wherein so much phrenite may be found. Taking the train from West Paterson to Little Falls, a walk of a few miles south brings us to the Little Falls, and here is another interesting locality wherein the contact of the sandstone and trap may be examined and the numerous additional phenomena studied. A quarry near the Falls is the best point in which to find these exposures, and from the viaduct crossing the river an excellent view of the surrounding country may be obtained. Regaining the train, Montville is soon reached and visited, and after this, if time sufficient Boonville, two miles west, may be taken in, or it may be necessary to go there to catch a return train, as but few stop at Montville. At Boonton there are many interesting features--iron works furnaces, localities in which fossil remains are found, footprints, conglomeritic beds, and many other things, of which I will endeavor to give a detailed account in some other of this series of articles.
