Book of Etiquette, Volume II
“ Invitations should be issued a week or ten days before the day set for the tea. Guests may include both sexes; but if there are only gentlemen, they may be invited verbally. The tea is served in the dining-room, or if he wishes, the host may have small tea tables laid out in the drawing-room. A silver tea service is always attractive and pleasing, and the host may pour the beverage if the guests are all gentlemen. If ladies are present, either the chaperon may pour, or a servant. Refreshments should consist of delicate sandwiches, assorted cakes and wafers, salted almonds, confections and tea. ”
