This has been a fair day - might have passed for [[underlined]] Fine [[/underlined]] without the clouds - [[underlined]] Very Fine [[strikethrough]] S[[?]] [[/strikethrough]] Sans, [[/underlined]] also, the strong wind that has been coming all day from the N.W.
Que-jes-se & the "Sailor boy" have not returned to-day as was expected by Capt B. The dogs & Kummiti are wanted by wh. another load can be sent over to-morrow. I am deeply engaged from Morn to night hour, usually to mid-night - in my surveying Astronomical & Navigation studies.
I wish to preserve the working of this proposition: - Required the observed altitude of the Sun this day at [[underlined]] h3-m30 PM Apparent time [[/underlined]] in [[strikethrough]] this (*Rescue Harbor) [[/strikethrough]] [*the following Lt. & Long:- ^[[Inserted subsequently July 28/63 Hall.] ]]
