'He'll take a chance' or 'clean the kitchen' meant an order of hash, 'Adam and Eve on a raft' was two poached eggs on toast, 'cats' eyes' was tapioca pudding, 'bird seed' was cereal, 'whistleberries' were baked beans, and 'dough well done with cow to cover' was the somewhat labored way of calling for an order of toast and butter.
