It is a curious fact, but nobody ever is sea-sick - on land. At sea, you come across plenty of people very bad indeed, whole boat-loads of them; but I never met a man yet, on land, who had ever known at all what it was to be sea-sick. Where the thousands upon thousands of bad sailors that swarm in every ship hide themselves when they are on land is a mystery.
