Any one who has been on the Rhine will have observed operations not unlike those to which we have just referred; and, indeed, most of the rivers of Europe flowing among their own alluvia have required similar treatment in the interest of navigation and agriculture. The levee is the crowning work of bank revetment, although not necessarily in immediate connection.

These subterranean vaults are usually filled in part with mud, pebbles, and breccia, in which bones occur belonging to the same assemblage of animals as those characterising the Post-pliocene alluvia above described.

Hence it was long and erroneously determined that bare rocks in the neighbourhood of shallow alluvia characterise rich placers, and that the wealthiest mining-regions are poor and stunted in vegetation. California and Australia, the Gold Coast and South Africa, are instances of the contrary. London, Crosby and Co., 1881.

Earthly deposits probably completed the disaster there were, it is said, both earthquakes and inundations and the soil was ever rising, the alluvia of the young Christian world buried the ancient pagan society.

The young man had not walked more than five minutes before he recognized the correctness of the directions he had received. The ground which he had passed over was a field covered with clumps of low trees; it was easy to see by its disc-like shape that it had been formed by successive alluvia, at the expense of the other shore, which had been incessantly worn away by the stream.

It is situated on a rising ground, just where the river Ybar enters the plain of Karanovatz. The environs are beautiful. The hills are of moderate height, covered with verdure and foliage; only campaniles were wanting to the illusion of my being in Italy, somewhere about Verona or Vicenza, where the last picturesque undulations of the Alps meet the bountiful alluvia of the Po.

I start with two Mason-bees of the Walls working at their nests on the pebbles in the alluvia of the Aygues, not far from Serignan. I carry them home with me to Orange, where I release them after marking them. According to the ordnance-survey map, the distance is about two and a half miles as the crow flies.

The Italians generally have not this paludal notion, for experience taught them long ago that malaria is produced nearly everywhere in marshy districts as well as in those which might almost be called arid; in a volcanic soil as well as in the deposits of the Miocene and Pliocene periods and the ancient and modern alluvia; in a soil rich in organic matters as well as in one containing almost none; in the plains as well as on the hills or mountains.
