THE AMEBIC AX X. ITER. I LIST [Vol. XLIII 



up the expedition under the auspices of the Carnegie Institution 

 to extend his researches on the desert flora, and on the journey 

 down to Mexico the author tells us of their visit to the famous 

 "Desert Botanical Garden" near Tucson, Arizona, of which 

 Dr. MacDougal was one of the originators, and from which 

 point the expedition outfitted. 



To those who have explored in the semi-arid regions of the 

 western states the account given by Mr. Hornaday of their 

 cross-country trip, recalls many familiar scenes. The cold morn- 

 ings, the blistering hot days and the delightfully cool evenings 

 are all features of a trip into the desert regions of the west. 

 All the scenes along the trail are brought before the reader by 

 pictures from pen and camera. The colored photographs are 

 especially striking. Botanists will find an interesting account 

 of the desert flora of southern Arizona and northern Mexico and 

 the zoologist will find a description of the few animals which 

 can manage to exist in this forlorn region. There is ever an 

 attraction in the desert; even the barrenness of things and the 

 apparent absence of all life make what little life there is all the 

 more interesting. 



On the arrival of the party near the Pinacate region a long 

 camp was made and short exploring trips were conducted from 

 the mam camp. This was made necessary from the fact that 

 the character of the country forbade further progress with the 

 wagons. At this place also occurred the onlv "row" of the 

 trip. Old campers know how painful it is to have a "row" on 

 in camp. It is painful for those immediately concerned and 

 for those who have to witness it. Their stay at Pinacate was of
