about six feet. Frequently the excavation makes a rather abrupt bend, in the form of an elbow, but I have often found it straight to the end. I believe the termination is a little higher than the entrance. The “nest was always in a sort of oven-shaped chamber, near the end, the bottom being a little lower than the floor of the tunnel.” I have never found any elaborate nest, the eggs in a majority of cases lying on the bare earth. On two occasions, however, I have found a bed of broken fragments of crawtish shells, and fish-bones; but never to my knowledge any sticks or straws, or, indeed, feathers except those from the body of the owner. I have never found the bird sitting on less than six, or more than seven eggs, and I do not believe the number ever exceeds the latter. Both sexes incubate, as I have caught both male and female upon the eggs.ROBERT RIDGEWAY.
GEOLOGY. KJEKKENMEDDINGS IN Iowa.-In November last, Mr. J. J. Kinersly of Keosauqua called my attention to some aboriginal relics he had discovered upon the bank of the Des Moines River, near that place, while the workmen were cutting the bank for a road to a newly established ferry, and digging a hole for the post which supports the ferry-rope. In digging this hole they passed about four feet through a layer of silt-like earth, crowded with the shells of Unios, before they reached the original surface. These shells are of the same species that now inhabit the stream, among which were recognized Unio plicatus, U. rectus, U. metanevra, U. crassus, etc. The locality is just above the mouth of a small creek, which has cut into the accumulation by the shifting of its channel, and leaves it without that symmetry of outline it would doubtless have possessed if it had not been disturbed. The heap is not above the reach of the highest floods of the river, and has evidently been largely composed of the silt brought down by the river and creek at the times of high-water. Mingled with and composing a large part of its bulk, are the shells which were brought from the bed of the river when the water was low - the only time they are accessible—and the mollusks were evidently cooked and eaten upon this spot during many years. The bed of the river opposite this spot is broad and gravelly, and an excellent habitat for the mollusks, while both above and below the bottom of the river is not so favorable for their growth.
No other shells besides Unios were found, although a few others may yet be discovered. Very few other kinds are to be found in the river near there. The bones of the deer are common among the shells, the marrow bones always being split open. Pieces of the carapace and other bones of the fresh-water turtle were also found. Among the implements found by the slight excavation mentioned, are one hatchet of greenish hornblendic rock, some fint arrow-heads and sharp-edged flints, probably used for skinning animals, and fragments of crude pottery. Some fragments of the latter bear evidence of having been burnt in contact with
organic matter, and were probably broken and spoiled while being used for cooking purposes. Fragments of charcoal were frequently found scattered through the mass.
The pottery is composed of common clayey earth intermixed with sand and slightly baked; some of the surfaces are rudely ornamented by cancellated scratches, and some are marked as if they had been enclosed while soft in a loose fabric or netting, probably of twisted bark fibres, the twist of the thread being easily distinguished.
The examination of this interesting accumulation has been very slight, but it is proposed to resume it next season.-C. a. White.
RHEUMATISM IN PREHISTORIC TIMES. - At the last meeting of the Pathological Society of London, Mr. Bush exhibited some specimens of pathological fossils. He exhibited a bone of a fossil rhinoceros which had been afflicted with rheumatism. He also exhibited a bone of a cave-bear, with a consolidated fracture, which had been broken just before the animal had hibernated; and another bone, of the same species of bear, which had been the seat of an osseous tumor.— Cosmos.
Disease also appeared among the reptiles of the Cretaceous formation of New Jersey, for Prof. E. D. Cope writes us : “I have just discovered a remarkable ally of Mosasaurus, which has a permanent functional dislocation of the ramus of the mandible. It has an articulation behind the middle, which has lateral and some vertical motion."
Disease is more common among the lower animals than is usually supposed. Prof. J. Leidy has exhibited to the Philadelphia Academy of Natural Sciences, pus globules from an abscess in the muscle of an oyster. - EDITORS.
Fossil PLANTS FROM GREENLAND. — Mr. Whymper has brought from the tertiary formation in Greenland, 137 species, of which forty-six are common to the European deposits of the Miocene Tertiary. Among the specimens are the cones of the magnolia, and the flowers and fruit of the chestnut. - Cosmos.
THE EARLIEST PLANT. — The discovery of Eozoön in the Laurentian rocks of Canada was of great interest. One of the most mportant discoveries recently made in palæontological science is analogous with it. It is the detection of what appears to be the remains of a terrestrial flora in certain Swedish rocks of Lower Cambrian age, - the supposed equivalents of our Longmynd rocks. A peculiar interest attaches to this discovery, inasmuch as it carries back the appearance of terrestrial vegetation upon the earth's surface through 4 vast interval of time, no landplants having previously been known older than the Upper Ludlow beds. The Swedish fossils now discovered appear to be the stems and long parallel-veined leaves of monocotyledonous plants, somewhat allied to the grasses and rushes of the present day. These plants apparently grew on the margin of shallow waters, and were buried in sand and silt, although it is probable that several species, and even genera, may occur in the sandstone blocks which have been examined. They are provisionally in
cluded in a single species, to which the name of Eophyton Linnæanum has been given. Eophyton, therefore, stands by the side of Eozoön, — the one being, in the present state of our knowledge, the earliest land-plant, as the other is the earliest animal organism. — Quarterly Journal of Science.
PROCEEDINGS OF SCIENTIFIC SOCIETIES.
HISTORICAL SOCIETY OF PASSAIC, N. J. – This active society was organized March 28th, 1867, and held its first field meeting July 13th, 1868, when glacial marks were discovered upon the rocks near Little Falls, running in a south-easterly direction.
ANSWERS TO CORRESPONDENTS. J. H. B., Camp Grant, near Richmond, Va.- The smaller of your plants is Selaginella opus. The larger is Hypnum tamariscinum. Both are found widely distributed through the United States.-J. L. R.
C. G. A., Augusta, Me.- Your insect boxes should be made as near air-tight as pog. sible to be insect proof. The cover should shut down upon an inner shoulder, so that au invading insect will have to make four turns in order to get fairly inside the box. The inside should be daubed with creosote; or camphor, wrapped in paper with pin holes, should be pinned to the bottom of the box.
S. P. M., Cold Springs, N. Y.- Agassiz's “Methods of Study” is a good introductory Book for beginners in Zoology, and may be read with Tenney's “ Zoology for Schools, Clark's “ Mind in Nature," and Agassiz and Gould's “Principles of Zoology.”
W. H. E., Coalburgh, W. Va. — The worm enclosed, which is two feet long, and the largest one we ever saw, is a gigantic Hair-worm (Gordius). Compare the account of the Gordius-like worm on p. 41. Also see Vol. I, p. 556.
D. M., Hamilton, Ohio. — The specimens are the “ Basket-worm, or larva of the Thyridopteryx cphemereformis, and will probably disclose the moth next spring. It feeds on vitrerent species of evergreens, and also on other plants, including the cotton.
F. P., Indianapolis, Ind. - The fern is Aspidium achrostichoides (a barren fron). It is common on shaded hillsides in the Northern States. We shall be pleased to get good specimens of the aquatic plants which we will have named for you. Send the set under numbers corresponding to those on the specimens you keep.
0.C.M., New Haven, and others. - Your papers for the Proceedings of the Chicago Meeting of the American Association for the Advancement of Science, should be sent to F. W. Putnam, Salem, Mass., quite soon, to be in time for printing. --F. W. P.

When the first Anglo-American pioneers, about the middle of the last century, explored the country east and north of the Tennessee River, the territory between the Ohio and Tennessee Rivers was a vast unoccupied wilderness. The rich valleys, hills and plains of Tennessee and Kentucky were crowded with a dense growth of forest trees and canes, and formed an extensive park, held permanently only by the beasts of the forest, and abounding with immense herds of buffalo, flocks of wild turkeys, droves of deer and innumerable bears. The nearest permanent Indian settlements were on the Sciota and Miami on the north, and on the waters of the Little Tennessee on the south ; and from these points the warriors of the Miami Confederacy of the north, and the Choctaws, Chickasaws and Cherokees of the south issued to engage in hunting and war, in this great central theatre. At this period, by common agreement of all the surrounding tribes, this section of country, which, for its fertile soil, numerous l'ivers and abundant supply of fish and game, was admirably adapted to the settlement of savage tribes, appeared to have been reserved from permanent occupancy.

great. Valley of the Mississippi, was inhabited in ancient times by a comparatively dense population, who subsisted by the arts of husbandry, as well as by the chase, is evident from the numerous depositories of the dead in the caves and along the banks of the streams in the fertile valleys, and around the cool springs which abound in this limestone region, and from the imposing monumental remains and extensive earthworks.
A considerable portion of the city of Nashville has been built over an extensive Indian graveyard,* which lay along the valley of Lick Branch. A large portion of these graves have been removed in the building of North Nashville. In this section of the city I saw a number of these stone graves, exposed during the digging of the cellars of a row of houses, and obtained a small stone hatchet, and another implement of hard, silicious stone, beautifully polished. This stone implement is supposed to have been used in the dressing of hides. All around the sulphur spring, traces of the aborigines are manifest in the form of fragments of large pots and various implements. It is supposed that this salt lick was frequented by the Indians for game and the manufacture of salt.
Extensive fortifications, several miles in extent, enclosing two systems of mounds and numerous stone graves, lie along the Big Harpeth, about sixteen miles below Old Town, at
* An extensive burying ground lies on the opposite bank of the Cumberland, directly across from the mouth of Lick Branch, and another about one and a half miles lower down; another at Cockrill's Spring, two and a half miles from the Sulphur Spring; another six miles from Nashville on the Charlotte Pike, and still another at Hayes. borough. Numerous stone graves are also found on White's Creek, on the Dickerson Pike, nine miles from Nashville, and at Sycamore, twenty-two miles from Nashville, on the plantation of Colonel Overton, and in and around Brentwood, at the Boiling Springs, and on the plantation of Mr. Scales. Extensive Indian burying grounds are also found in White County, near Sparta, and along the various streams flowing into the Cumberland and Tennessee Rivers, as Harpeth, Duck, Elk and Stone Rivers. At the plantation of General DeGraffenreid, two and a half miles above Franklin, numerous stone graves are found within extensive earthwork, which appears to have rounded a considerable Indian town. One large square mound, 230 feet in diameter, together with a chain of smaller ones, are found within the ancient fortification, with mounds and stone graves. One of the most remarkable stone-grave burying grounds is found on the west fork of Big Harpeth, six and a half miles from Franklin, at a place called Old Town, the property of Mr. Thomas Brown.
