 passed since any one had been able to make a landing at 

 the proper season. My own party attempted it unsuc-

The amount of wearing down of the middle peak and 

 consequent lowering of the ridge as a whole between 1873 

 and 1890 may be seen by comparing Ball's sketches (figs. 

 8 and 9) with a photograph taken by the t Albatross,' in 

 1890 (fig. iz). 1 The apparent thickening of the base and

 ridge. 



In 1884, according to Cantwell, the great north cliff rose

 be completely made out (fig. 13), but the lowness of the 

 ridge as a whole, the small size of the northwest peak, and 

 the depth of the notch separating it from the rest of the 

 mass,told too plainly of the rapid wasting going on and fore-
