He was also the telegraphist.

Mary Rotheram, who had taken lessons in cooking, was chief cook, and she was to be helped by Janet.

Jack was superintendent of the washing-up, and Horace Campbell was his principal ally.

(How tired they got of it!) Jack, Horace, and Robert were carriers between the grocer's, the butcher's, the baker's, and the Slowcoach.

Mary Rotheram should be his companion, and ask for eggs and milk at the same time.
Next came the victualling, and this was exceedingly interesting, although it made great holes in the sovereign box.

Janet and Mary Rotheram sat for hours over the Stores List, and they were continually taking important questions to Collins.
"How many tins of mustard ought we to take?
A dozen at fourpence ?" "Mustard, Miss Mary?
Why, two penny ones would be enough for a month." (Three and tenpence saved, you see.) "I say, Collins, how long do eggs boil ?" "Collins, you have to prick sausages, don't you, or else they burst ?" "Collins, how many loaves do eight people want a day ?" "Four, Miss Janet, at the least--large ones." "Including Kink ?" Janet explained.
"Oh, Kink too! Five, then, if not six, the old gormandizer." "Collins, what's the best part of beef for stewing ?" "Collins, you can put anything into a stew, can't you?
Absolutely anything ?" "Collins, if you've put too much pepper into a thing, is there any way of getting it out again ?" Mrs.Avory was very particular about tinned things.
