The full account begins on p. 275 with multiple observers, including from the Washington Territory, “The outline of Mount Rainier was more distinct before the eclipse than it had been at ally time during the preceding three weeks.”

Some observations are more poetic than others and one observer didn’t see anything, “I was prevented from observing any of the astronomical phenomena during the totality.”

Another was overwhelmed:

The progress of the moon’s passage across the sun’s disc was beautiful in the extreme, and at the period of totality there was the most gorgeous sight I ever witnessed.
