From these results, Mr. Sidell concludes "that the earthy matter is deposited more suddenly than 'would be the case if it depended on the check of velocity alone; that the bars will be formed just at the debouches, or where the salt water is first met; and that the greater the quantity of water brought down, the sooner, on account of the sudden precipitation, will the bars be formed at the debouches." 'Experiments on Rates of Deposit of River Silt.--The results of Mr. Sidell's experiments were brought to the Author's notioe in 1894, by some correspondence on his Paper on "The Training of Rivers," contributed by Mr. J. V. Wilfrid Amor;1 and the results appeared sufficiently remarkable, and the subject of the influence of sea water on the deposit of silt of adequate interest, in regard to the formation of deltas, to merit further investigation. Accordingly, samples were obtained by the Author, in 1894-95, of the silty sediments of the Bhone, the Danube, the Dnieper, the Nile, the Hugli, and the Mississippi.2 The silt from the Dnieper was sent in place of silt from the Volga which had been asked for by the Author; but though the Dnieper is not a deltaio river, the sample of its silt possesses the interest of differing materially in composition and rate of deposit from the samples of silt from the other rivers. Cylindrical glass tubes, 4 feet long, and between f inch and 1 inch in diameter, were employed for the experiments.
