...means of many plans and photographs Professor Dorpfeld sought, with marked success, to give his hearers a picture of the results of the excavations. Nine strata had been found one over the other, marking the site of nine different settlements, each of which in its turn had been destroyed. In the upper stratum Roman buildings were uncovered, including a stately temple of Athena built of marble, and three theatres, and many colonnades and houses. Countless marble inscriptions record that this city was called Ilion, and that some of its buildings were erected by the Roman emperors. Under these Roman buildings...
...Department of Geology is preparing to send a party to Gay's Head, Martha's Vineyard, during the April recess, to examine the formation of the cliffs on that headland. The clay and sand strata of this section abound in fossil bones of the order of Cetaceans, to which the whale and the walrus belong. There are also leaf-beds of a representative of the order to which the gigantic red-woods of California belong...
Technology has sent a geological excursion into Western New York for the purpose of collecting fossils and studying their occurrence in strata...
...main clues to the great geological movements. They represent the tracts of country which have been formed the longest, parts of them having always remained above water. The sediment washed by the sea from these protruding tracts has formed lime-stone and sand stone about their edges and the strata of these rocks is therefore much thicker here than in regions like the Mississippi basin which have been often submerged. One of the great theories of mountain formation takes these sedimentary rocks and their overloading of the earth's crust for the cause of the uplifting. The study of such...
...complete account is given of the development of the apparatus and of the methods employed in dredging. Several improvements were invented by Prof. Agassiz. The results of his study show that the changes of elevation have been very slow and slight, with very little disturbance of the strata, and that the eras of depositions, from the Eocene to the present time, have been marked by the same processes which, even now. may be observed in action...
