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
