Had Divine Service. Have only seven hymn-books, those brought on
shore for our first Service being very stupidly taken back to the ship.
I begin to think we are too comfortable in the hut and hope it will
not make us slack; but it is good to see everyone in such excellent
spirits--so far not a rift in the social arrangements.
_Monday, April 24_.--A night watchman has been instituted mainly for
the purpose of observing the aurora, of which the displays have been
feeble so far. The observer is to look round every hour or oftener
if there is aught to be seen. He is allowed cocoa and sardines with
bread and butter--the cocoa can be made over an acetylene Bunsen
burner, part of Simpson's outfit. I took the first turn last night;
the remainder of the afterguard follow in rotation. The long night
hours give time to finish up a number of small tasks--the hut remains
quite warm though the fires are out.
Simpson has been practising with balloons during our absence. This
morning he sent one up for trial. The balloon is of silk and has a
capacity of 1 cubic metre. It is filled with hydrogen gas, which is
made in a special generator. The generation is a simple process. A
vessel filled with water has an inverted vessel within it; a pipe
is led to the balloon from the latter and a tube of india-rubber is
attached which contains calcium hydrate. By tipping the tube the amount
of calcium hydrate required can be poured into the generator.
