The Art of Travel; Or, Shifts and Contrivances Available in Wild Countries
“ It is convenient to sink a large barrel into the flat marsh or mud, as a dry place to stand or sit in, when waiting for the birds to come. A lady suggests to me, that if the sportsman took a bottle of hot water to put under his feet, it would be a great comfort to him, and in this I quite agree; I would take a keg of hot water, when about it. If real ducks be used as decoy-birds, the males should be tied in one place and the females in another, to induce them to quack. An artificial island may be made to attract ducks, when there is no real one. ”
