case if it had been exposed to the weather for more than 
one or two centuries. Moreover, there is no change in 
the vegetation at this point. The alder thickets which 
begin at the head of Disenchantment Bay, characterize 
the slopes of the mainland not only to Haenke Island but 
for miles beyond, and the first spruces noted were not less 
than five miles to the south of the island. But while the 
ice seems to have recorded neither a maximum nor a pro¬ 
longed lingering at the point where it was earliest observed, 
our present data suggest no other line of critical impor¬ 
tance. We can only say that for a period considerably 
greater than a century the general character of ice change 
has been diminution. 
Since the last paragraph was written, the U. S. Coast 
and Geodetic Survey has published a new chart of Yaku- 
tat Bay, giving soundings from the ocean to Point La- 
touche, six miles below Haenke Island. These sound¬ 
ings give no indication of a moraine in the vicinity of Point 
Latouche. Not far from that point there is a depth of 
1,000 feet, and thence southward the channel is shown for 
five miles. Here, at a distance of twelve miles from 
Haenke Island, is a submerged bar with a depth of about 
300 feet, and this is probably the last-formed important 
moraine in the bay. There appears to be another oppo¬ 
site Knight Island, seventeen miles from Haenke Island, 
the intervening hollow having an extreme depth of about 
600 feet (see fig. 27). 
This is the greatest distance to which the channel of 
the Hubbard, or Disenchantment Bay Glacier can be 
clearly distinguished. Its course is not central to the bay 
but nearer the eastern shore, the Disenchantment Bay 
stream apparently having been crowded over by the ex¬ 
pansion of the Malaspina Glacier, which then included the 
Lucia. Farther to the south and southwest the soundings 
reveal a series of troughs and ridges whose trend and
