ALASKA GLACIERS 
The front of Johns Hopkins Glacier has suffered less 
change since Reid mapped it, but there has been some 
retreat. A comparison of photographs made in 1892 and 
1899 shows that more rock is exposed at the south; and 
a remnant of ice I could see clinging to the mountain side 
at the north showed that the front had within a very few 
years held a position several hundred yards more advanced 
than in 1899. Its determined changes were so small that 
no attempt has been made to express them in the accom¬ 
panying diagram. 
The remaining glacier of the three was indicated in a 
general way on Reid’s map of 1892, but its lower end was 
represented by a dotted line, implying doubt as to its pre¬ 
cise position, and no name was attached. It was more con¬ 
fidently delineated by the Boundary Commission in 1894. 
As my map and photographs give such determination of 
the position of its ice cliff that future changes can be meas¬ 
ured, it seemed proper to supply Reid’s omission in re¬ 
spect to name, and the Harriman Expedition adopted 
the name Reid. I 
am glad to be able to 
illustrate somewhat 
fully a feature bear¬ 
ing a name so de¬ 
serving of honor in 
Alaska glaciology. 
As already men¬ 
tioned,the Reid Gla¬ 
cier was a branch of 
the Grand Pacific in 
1879, but not many 
years could have 
elapsed before the recession of the latter made it indepen¬ 
dent, and it is probable that its end then projected some¬ 
what beyond the general line of the south wall of the
