October 26, 1926* On the plains passed over there was much high 

 water the last of September, and everywhere washouts and ground scored. 

 Soil is sandy and reddish mostly. At Queribabi our train stopped, small 

 station with water tank. Many cars, autos, waiting. Waited almost an 

 hour and then hired a boy with a Ford to take me to Carbo, 44 miles, 

 for 20 pesos. Road goes through a fair but biunpy country, winding 



heavy 



gulches recently made 



climbing over trees (Cardiospermum). Fruit looks like an apple but is 

 l)laddery. Also saw for the first time a chimney cleaner Cereus they call 

 viejo (old man) because it has a long and white beard all over, 10-20 

 feet high. Other Cereus also frequent. No Cereus giganteus. Mesquit 



common, also Condalia. Low shrub with dossv leaves

Fouquieria. 



^^^bo, 1,500 feet altitude. This had been quite a little to^vn wth 

 II a dozen stores and some houses along the track, but half of them 

 had fallen down in the last rain. I botanized some while waiting for 

 the tram to pull out the next morning. I found Fouquieria penin^inan'? 



cojnmon also a low Cereus a few feel high, and the two Opuntias, al=o 

 he bottle-brush Cereus once in a while. The green palo verde was in 

 leaf and resembled a Parkinsonia. Cardiospermum was here a^.^o. As w- 

 pa.ssed down toward Hennosillo the ground became flatter, more ssndy, 

 and the shrubbery not so thick, but the same sprcies. Everybody was 

 mterested m my valise, which was recovered, but few could talk Erx^Msh. 

 and I could not understand much Spanish. The Fouquieria peninsularis 

 IS rarely 10 feet high and is now so leafy that it reminds one of Lvcium.
