THE VOYAGE OF THE HASSLER 119 
kept a record of the expedition such as she made for the Bra- 
zilian journey. This diary, however, was not fully prepared 
for the press at the time of Agassiz’s death and has never 
been published as a whole, although portions appeared as 
three articles — The Hassler Glacier, In the Straits of Ma- 
gellan and A Cruise through the Galapagos — in the Ailantic 
Monthly for October, 1872, and January and May, 1873; 
other parts were also published by Mrs. Agassizin her biog- 
raphy of Agassiz. Since a fuller record of the voyage, re- 
plete as it was with unusual experiences, is worthy of pres- 
ervation, and since Mrs. Agassiz’s part in the company is 
highly characteristic, extracts from her letters that supple- 
ment the published accounts are given here, although some 
of them have less personal than general interest.

is busy, of course, and he has begun as before on the 
Colorado to lecture on the work of the day, only here 
he lectures on deck. This morning I sat with my back 
to the little audience, but the Captain told me that 
nothing interested him more in the scene than to
