 may form an idea of the waste I passed through during 

 these five davs, that all the water we had durinsf our 

 trip, extending over about 120 miles of country, is all

 thing did I see, not a bird, not even a lizard or an 

 insect, and the only living thing was here and there 

 a sickly cactus growing on some hillside. Yet the whole 

 country shows signs of the existence of large rivers 

 which have cut deep canons between some of the hills, 

 and the whole desert is probably an old lake bottom 

 which has left its trace by the extent of salt and soda 

 to be found in all directions. 



Kiss the boys and love to all. Good-bye,

 paraiso, and as I spent most of last week on horseback, 

 riding from thirty-five to forty miles a day, and not 

 faring remarkably well either for food or shelter, it was 

 quite a comfort to be back again on board ship. But
