A variety of' <br />water-birds, such as sand-hill cranc, s)1ipe, ducka, geese, &c,; Tho Cenms ma- <br />cro/is were occasionally to be seen; the Lepus cullolis was quite abundant; also' <br />the Canis lulrnns. <br />On the desert of the Colorado there is but ]illle growing, excepting greaae- <br />weed. On it are to he found tho remaina of old Jlnodo1lS, showing that it is sub- <br />ject to be over(\o\\'cd by the Colorado; but I believe there was hut one epecios, <br />of that .hell. It i. singular that in the Great Colorado and its tributaries I did <br />not procure or see a .hell of the genua Unio. At New river there are numerous <br />mesquite trees and careless-weed, (Chenopodium,) the sced of which the Indians <br />grind and makc into bread. The laguna of this'creek was filled with an infer- <br />nal water, being green, thiek, sa]t, and stinking. In and about this we found a <br />number lIf ducks and small snipe. <br />As we al'pr,oached Curissa creok, we found fossil oyster-shells, (Exogyrn)., <br />On the hills nbuut this creek were growing numcrous cneti ; also the St. Jo- <br />seph rod, (.Follllern s]linosn,) which heing in 1\111 bloom. luoked boautiful. 1\Iea- <br />qnite, IlHow-wood, IIl1d salL grnss, were nbundllnt. On this creek tht;re ha! <br />bcen II grove of jarge palms, fl'few of which now remain. <br />At Vnlliecit,," we fonnd plenty of graSl!, anf the .f1gnvI Jlmericnua, growing <br />abundantly. <br />Ascending the Hiley from San Felipe, tho mOlllltains on either side nre.cov- <br />eredwith tall pines. On the dividing ridge we found a specie. of live-oak, <br />(Q"CTCIIS agl'ifolin,) and tho button-wood, (Plalan1lS Mcxicanus.) There was but <br />little vnrialion in the vegetation between hercand the Pacific, excepting many <br />of the hills were covered with wild oats. Being lato in the season, and,snowon <br />the Coast \'ange, thcre were no plante to be collected. Birds wero scarce. <br />N eur Snnta ISilbelle, ill a large laguna, there were a number of ducka, among' <br />them tho canvass-back (J;Yl'oca ValiSlleria,) red-neck, (.Y.Jcrilla,) mallard (.f1nlU <br />Doscllas,) teal (Plc'roeyallea cll,"Ulwln,) &.c.. <br />For Inlier anll 1110re detai]~d accounts of the natural history, I will have to <br />refer JOu to the scp'lrate papers on ea.ch branch flecompanJing this. <br />I mllst here olrer my grateful acknowledgments to the kind assistance afford- <br />ed mo hy Bdward Hallowel, M.1J., and Professors Torrey, Baird, and Girard, <br />in their varions departments of natural history. <br />To the Messrs.
