Moreover, it "changes color." As though "caught doing wrong," it changes color and blushes at times a rosy red. This is the hue of multidunious veins: "A thousand streams rolling down the cliffs on every side, carry with them red sand; and these all unite in the canyon below, in one great stream of red mud" (n. 50.) But sometimes the color below Yuma is yellow or black (n. 51.) The name "Colorado" is a Spanish term conveying the idea of redness, and undoubtedly this hue predominates throughout the course of the boisterous stream; but other colors due to the dye or wash of variously painted cliffs, are also met with. Moreover a section may exhibit one color to-day and something different to-morrow. And so it is with the gulf, which receives the Colorado, and on which floating patches of color are frequently seen. Truly our Gulf or Estuary is remarkable for both its coloring, blue, red, etc., and its changes of color. In all respects it is plainly a =Puh-hai=. Our Gulf or Estuary is also called a =yuen=. Farther on (see Chinese version) we read that the Canyon river produces or grows into (=shang=) a beautiful (=kan=) =yuen=. This term =yuen= stands for a "gulf, an abyss; an eddy, a whirlpool or place where the back water seems to stop." A whirling, violent, or impetuous body of water is evidently referred to. Fernando Alarchon, in 1540, found the Colorado "a very mighty river, which ran with so great a fury of stream that we could hardly sail against it. One voyager tells how his ark, the "Emma" was "caught in a =whirlpool=, and set spinning about." Here is a =yuen=. Again, "The men in the boats above see our trouble but they are caught in whirlpools, and are spinning about in eddies." What have we here but =Yuen=--multiplied whirlpools? Through "Whirlpool Canyon" and all the way to the Gulf, the waters dance around and about. We read of "dancing eddies or whirlpools." There are more than 600 rapids and falls in the Colorado (n. 52.) The waters =waltz= their way and even furnish their own "rippling, rushing, roaring music." And we are in addition told of "innumerable cascades adding their wild music" (n. 53). Surely the entire inlet traversed by the bore or reached by ocean tides is in precisely the condition of commotion which may well be designated by the term yuen. We are informed that the =kan= (or beautiful) =yuen= approaches (=tsih=) with vapor (=hi hwo=) and bathes (=yuh=) the sun's place (=ji chi su=). It is evident that the mighty stream which traverses the Great Canyon in the region beyond the Eastern Sea, should flow from a Bottomless valley to a Gulf, and reach to the Sun's Place. And we find that the current of the Colorado extends to the Tropical line of Cancer, which crosses and marks the mouth of the Gulf of California. Vapor or fog is noticed in connection with the beautiful (even if restless or reeling) =Yuen=.
