ing all that has already been observed on this 
point, Dr. Peale has had by no means a light 
task. So many accounts have already appeared 
of the more remarkable geysers and springs, 
that their main features have become more or 
less familiar to all, in so far as they can be made 
so by description. The Giant, Castle, Grand, 
Old Faithful, Giantess, Bee-Hive, and others 
of the best known geysers, are included in the
