Emoryi ? but very rare. I also saw » Passiflor* 

 Lantana, » cucurbit vine, lanusia, Dalea with ver)? 



mcamata, 3 sptcies of Boerhaavia, Boutelous 3 ^cles 



S«taria gUuca, Jevil-grass, Anxbroaa pailostacbya ? Amaranthu* fimbriatus. 



Santa Rosalia. There is a copper smelter of 1,000 tons a day. The 

 ore 18 a carbonate in Tertiary conglomerate, beach fomiatlon, and for Ai3 

 Tt&gaa is very recent in origin. They have made an artificial harbor of 

 concrete. There is « long whale-bact, ten miles long and several miles 

 wide, of sedimentary and sandy days that arises on the east side of 

 volcanic peals, or a range, which I assume is a part of the San Pedro 

 Martira. ^ Vegetation is about the same as at Victorville, California. 

 Fouquima pemnsularis, Lsrrea, Jatropha shrub. Porophyllum 2 species. 

 Bigelovia species but wi^ 4-angled fruit, with pubescent leaves, 4-6 feet 

 high, Prtalonyx 2 feet high, Mesquit, Encelia farinosa, two species of 

 Euphorbia, Croton Boerhaavia annual. Saw no Boutelouas. Setaria 

 glauca occurs here. Saw three pelicans, one with white head and neck 

 and blue body, one gray all over, one nearly black. A jumping fish 

 about a foot long. Saw two porpoises at Guaym 



November 5, 1926, Muleje. The landing has one house, and a ligbt- 

 fiouse up on a rock. The town is three miles up the creek to the south. 

 It is a little land-locked bay. Dates grow close by at a ranch, Spirosta- 

 rhys, a 4-angIed fruited dirub on the beach, Encelia fainora, a Cereus, 

 long and straggling on the ground on the rodcs. Also a prolifcra 

 Opuntia. B^low Santa Rosalia the first stop was at a penal colony on 

 an island where there was interesting vegetation, a pile landing. Then in 

 Jj^ night wc came to Muleje. Very, very dry hfre. Saw bottle-brush 

 Cereus, Encelia very common, Fouquieria penin'sularis or splendf^r^s. can't 

 he sure. They were cultivating a tree cotton. Saw a few Cereus Prin- 

 fflei, a Pcrityle like a dirysanthemum (probably a HoffmciJteria.). » 

 1 orofOiynuni shrub, Begelovia same as Santa Rosalia. Saw an onpa t'f- 

 .eaves shrub in the water for the first time (Rhizophoms Mangle), fyi^vf 

 • thick leaved Lycium, also a perennial Salicomia on flats, a Datura 

 Stramonnium, very prickly. 



Morning, on waking we are pas.sing a low area, valleys, with hilU 

 farther back. Then this area drops down into a plain which goes back 

 to some lofty mountains, 5,000 feet more or less high, ninning parallel 

 wAth the coast but some ten miles back. There seems to be a wide tract 

 or valley buttmg on to the mountains, which are sedimentary and palaef>- 

 joic, may be Cretaceous. Then comes a sharp escarpment 1.000 to 2,000 

 ffet altitude <a fte coast mostly sedimentary, but the main range con- 



^ues south. The costal area bmkj away into a mesa or low hills. 

 Then comes a h^gc island on the east. Then Loreto lies ahead ten miles 

 -lore or less. Vegetation scattered on the hills but denser on the pfain? 

 llie giant cactus (Cereus Pringlei) is thickly covering the plain. Therf 

 J re no oAer fam. Thert «e jagged mountains on th? mainland, being » 

 h tie to the northwest, but all stratfied nearly horizontally. There is an 

 ;5]and about 20 tmhs long to the east and we pass between it and the 

 mainland as night falls.
