Miramichi River

“ After advancing about ten miles in a south-east direction from Berberah, we entered rough and broken ground, and suddenly came upon a Fiumara about 250 yards broad. The banks were fringed with Brab and Tamarisk, the Daum palm and green rushes: a clear sparkling and shallow stream bisected the sandy bed, and smaller branches wandered over the surface. This river, the main drain of the Ghauts and Sub-Ghauts, derives its name from the increased volume of the waters during night: evaporation by day causes the absorption of about a hundred yards. ”

“ At last, after no end of doubling and hiding and riding in a triple loop, and making use of every device known to a scout for destroying a spoor—it took us about three hours and a half to cover as many miles—we reached the river, and found it a yellow flood two hundred yards broad. In the way African rivers have, the stream, four feet across last night, had risen from the rain. ”

“ After the Parana and the Amazon, it is the largest waterway in South America, and, for the volume of water it carries into the ocean, it ranks with the Mississippi, the Congo, Yang-tse-Kiang, and the Brahmaputra. Well have the natives of the lands through which it flows named it the Great River—for it is great in every way—great in the immense basin it drains; great in the tribute it carries to the ocean, and great in the number and magnitude of the rivers it counts among its affluents from the distant Cordilleras. ”

“ The Japanese would begin at the right end of the problem, and build big enough at the start to solve it as a whole, comprehensively. Their plan would be to use up every drop of the flood water by irrigating land with it. There would never at any time of the year be any water running to waste in the lower river. There would never be in the main river more than enough water to supply the canals that irrigated the lowlands of the lower delta. The ship canal from Yuma to the Gulf, and the canals from Yuma to the Needles, Phoenix, and Florence would be not irrigating canals, but drainage canals. ”

“ On this part of the river, boats are much exposed to danger from the falling banks, which are called “tierras disbarrancandas.” The Mamoré, and indeed all the rivers of the Beni valley, are for ever shifting their courses in many parts of the forests through which they flow. They undermine the banks on one side, which, falling away, form the numerous curves on the convex side of which the mud and sand brought down by the current is deposited, and playas and banks are formed, on which a forest grows in course of time. ”

“ Thence the vast stream sweeps boldly into the south, and with a rush discharges down the rapids, and straight over the line of precipice, in a vast tumultuous greyish-drab torrent which speedily emerges into comparatively still water below. The rock here is an exceedingly hard, mottled limestone, resembling the stone at St. Andrew's Rapids on Red River. Where exposed it is pitted or bitten into by the endless action of wind and water, and lies in thick layers, forming an irregular dyke all along the shore, over the surface of which passes the portage, some forty yards in length. ”

“ The majority of the board, 8 to 5, opposed the idea of a dam and locks at Gatun on two grounds: first, that the introduction of locks in a treatment of the question was objectionable from many points of view; and, second, that the maintenance of a summit by means of an earth dam of immense magnitude to control the flood waters of this river introduced an element of great danger since the dam, without sheet piling, was proposed to be founded on the alluvial-filled gorges of the Chagres River, where the depth at one point extended 258 feet below the level of the sea. ”

“ With drooping reins we rode slowly on till we got to the river, now no longer the shallow stream which in summer one can wade over knee-deep, but a broad torrent, which eddied, swirled, and foamed, as it dashed rapidly over its stormy bed through banks which were already growing too narrow for its swollen waters. In the middle we could still see a single tuft of long grass, which was bending with the current, and this, Isidoro told me, grew on a little island, which when the river is fordable, 118 is several feet above the water's level. ”

“ The Nile never flows over the top of the dam, but always through the gates and the canal at one side. When the gates are closed during the dry season, enough water is held back by this structure of steel and granite to form a [133] lake over one hundred miles long, and this is let out as needed to supplement the ordinary flow of the river and give the crops plenty of water all summer through. There is water enough in the reservoir to give all the families of the United States all they could use for four or five months, and enough to supply Great Britain and Ireland the entire year. ”

“ This tree resists the action of air and water longer than any other, and, if not submerged throughout the whole year, will retain life for an extraordinary period. Lake Bistineau, as well as Black Lake, Cado Lake, Spanish Lake, Natchitoches Lake, and many others, have been formed, according to Darby, by the gradual elevation of the bed of Red River, in which the alluvial accumulations have been so great as to raise its channel, and cause its waters, during the flood season, to flow up the mouths of many tributaries, and to convert parts of their courses into lakes. ”

“ Its waters are intensely bitter, and of a milky colour for many miles from the source; the bitter taste of the mineral substance which the water holds in solution is quite appreciable at the mouth of the river after a course of about seventy miles.
It was down this river that the wonderful avalanche of ice and mud forced its way from Ruapehu to the sea in 1863, scouring out the bed of the river, destroying a bridge, and doing great damage to the native cultivations. ”

“ Further up, near Bhamo, in the defiles, the mighty river has forced its way between high mountains which rise suddenly from the water’s edge, and the scenery there is majestic. Numbers of villages and small towns are seen on the banks of the river, for here, as elsewhere, the fresh water of the river means life to man and beast, and verdure and freshness to the crops irrigated from it. ”

“ It rises in the Western Ghauts, and flows for the greater part of the year a placid, shallow stream. But when the monsoon rains overflow the watersheds, it fills with a sudden, magnificent rush; you can hear it a mile away.
Out in the sandy river bed a number of high stone platforms are built, which are used by travellers as resting-places when the river is low. Some years ago a party of labourers, being belated, decided to sleep on one of these platforms ”

“ The tract itself is a vast plain, dotted with homes as far as the eye can reach, with great irrigation canals like rivers meandering through the land, carrying a volume of water 70 feet wide and 7 feet deep, and capable of being navigated by river steamboats if it were considered advisable. Visit the Minadoka dam, which is just being completed by the Government, and which is designed to irrigate 100,000 acres, if you would learn that there is no mechanical obstacle, however great, that American ingenuity will not overcome. It is one of the wonders of the world. ”

“ A change, however, in the land, seems to commence near this place, and it assumes here very much the aspect of red clay, but in some parts the sandy soil predominating, and all lying very irregular, except immediately upon the streams.
I was impressed with the adaptation of the Jundiahi river, a small stream which runs near our inn, for the location of machinery of limited water-power; and when the railroad reaches this place a good mill or cotton ginning establishment would be likely to prove very advantageous on this river. ”

“ Any weakness in the Gatun Dam would ruin the whole project. You can see, of course, why this is so, because the water in that Gatun Lake will be relied upon to fill the locks which will raise vessels up or down.”

“But suppose the Chagres River cuts up ugly, as you said it does sometimes?” asked Merritt.
“Well,” said Rob, “I heard Mr. Mainwaring say that the great lake will be so big that a flood would affect its level no more than a cup of water poured into a bath tub. The river will merely serve to keep the lake filled and supply the water needed to work the locks.” ”

“ But the truth is that it forms a watercourse dependent at present upon floods, admitting of navigation for hundreds of miles at certain seasons, and at others being as dry as the Arno at Florence or the Manzanares at Madrid. By a series of dams and canals this river might be navigable all the year round. The same remark applies to several of its tributaries, and to rivers generally running toward the inland centres [Pg 236] and flowing into the Murray. The governments of the several colonies have long realized the importance and the necessity of a grand and comprehensive system of irrigation. ”

“ Perchance, after a few thousands of years, if the fishes will be patient, and pass their summers elsewhere, meanwhile, nature will have levelled the Billerica dam, and the Lowell factories, and the Grass-ground River run clear again, to be explored by new migratory shoals, even as far as the Hopkinton pond and Westborough swamp. ”

“ Except during the period prior to the annual rise, when the Blue Nile is practically dry, and the waters of the White Nile fill the empty channel, the stream of the eastern river, being much stronger than that coming from the west, forces the waters of the latter right across the western shore. At all times the effect of the meeting of the two rivers is a striking one. In flood the Blue Nile brings down an immense volume of chocolate-coloured water, and holds back the discharge of the White Nile, ponding this river up and flooding the marshes for many hundred miles up-stream of the junction. ”

“ The temple of the speaker was in ruins long before Spanish days.
Like other streams of the west coast, the great river Rimac has run through the gamut of all zones. Hurrying down from the cordillera, it spreads fertility far and wide over the dry shore-valley. As far away as Chorillos, “little water jets,” the water of the Rimac filters through, led astray for irrigation. But its own journey to the sea is vain. The mountain water is so precious to the desert that by the time the stream has reached the shore, it has not force enough left to make an outlet across the beach into the ocean. ”

“ Therefore, if the present major streams reach the sea, it may also be concluded that those of an earlier period reached the sea, provided the topography indicates the perfect adjustment of streams to structure. Lacustrine sediments are absent throughout the Tertiary section. Such through-flowing streams, discharging on a stable coast, would also have mature valleys as a consequence of long uninterrupted erosion at a fixed level. The Majes river must have cut through the Coast Range at Camaná then as now. Likewise the Vitor at Quilca must have cut straight across the Coast Range. ”

“ Finally, Captain Speke made his own lake a physical impossibility. Within little more than 60 miles from east to west he has given it three main effluents, the Mwerango, the Luajerri, and the Nile or Napoleon channel, to say nothing of the Myo Myanza, the Murchison Creek, the Usoga stream, together with the Asúa river from the Baringo. ”

“ First, the prevention of floods and second, the improvement for navigation. In dealing with the first aspect nothing could be better than deepening the river by dredging. In the improvement of the Canton Approach and Harbor and also of the Canton Delta, we have to cut a deep channel right from the deep sea up to Sainam. In the improvement of the lower part of the North River, we have simply to continue the cutting process higher up until we have a deep channel, say 15 to 20 feet as far as the Tsingyuen Gorge, either by artificial or natural means. ”

“ Presumably the upstream migrants reaching fish ladders might at one time be presented with water from one river and at another time water from the other river. If water quality is important in attracting the upstream migrants to their proper streams, as many experts believe, this stratification would be a source of confusion and delay. Also a source of confusion to the upstream migrants would be the predicted tendency shown by the record for water from the Salmon River arm of the Nez Perce reservoir to flow up the Snake River arm and vice versa. ”

“ Davis suggests that a great derangement of waters of the Yellow River, one of the largest in the world, might even now cause the flood of Yaou to be repeated, and lay the most fertile and populous plains of China under water. In modern times the bursting of the banks of an artificial canal, into which a portion of the Yellow River has been turned, has repeatedly given rise to the most dreadful accidents, and is a source of perpetual anxiety to the government. ”

“ Warping may be resorted to during the flood season to raise the level of adjacent low-lying fields, rendering them at the same time more fertile. Where the river is running above the adjacent plains there is no difficulty in drawing off the turbid water by gravity, under controlled conditions, into diked basins, and even in compelling the river to buttress its own levees. There is certainly great need and great opportunity for China to make still better and more efficient her already wonderful transportation canals and those devoted to drainage, irrigation and fertilization. ”
