|Manners and Customs of Polite Society (1896)|
"The bachelor women in their cosy little city apartments, or even their one apartment, refuse to be debarred from the pleasure and privilege of giving the little entertainments so dear to the heart feminine. They not only give the most charming little "teas" and "coffees," but they are past masters in the use of the chafing dish... A sandwich spread is another entertainment easily given by a "bachelor maid." This is a meal at which everything, barring the tea and coffee, is served in the form of a sandwich. Not until one has tried does one realize to what excellence and variety this form of viand lends itself. Deviled ham sandwiches, egg sandwiches, cheese sandwiches, lettuce sandwiches, potted ham, potted fish, potted cheese sandwiches, pineapple sandwiches, peanut sandwiches, cucumber sandwiches, tomato sandwiches, walnut sandwiches, oyster sandwiches and so on indefinitely."
