Space allotted to the invertebrate animals, remarkably free from errors.

J. D. Parry, President of the Eastern Division of the Union Pacific Rail- 
road, giving a detailed account of the EAN voyage of James 
White of Callville, through the Grand Cañon. It seems that a party of

Grand River. Two of them escaped, built a raft and embarked upon it, 
miles beyond they passed the mouth of Green River, and were in 
Colorado proper. Henceforth their way lay through oa sullen and 
hitherto untraversed depths of the Grand Cañon, whose precipices gradu- 
d 
These swept off Henry Strole, and all the PrO TINADI SP White 
pursue the voyage alone. One A aan and eighty miles farther on z 
passed the mouth of the Colorado Chiqu
