The answer is as follows: "Miss G---'s compliments to Mrs. L---, and accepts with pleasure her kind invitation for Wednesday, March 7th." Or, "Miss G--- regrets a recent death in her family will prevent her accepting Mrs. L---'s kind invitation for March 7th." An invitation to an evening party is worded: "Mrs. S--- compliments to Mr. and Mrs. T---, and requests the pleasure of their company on March 9th, at 8 o'clock." Such an invitation calls for full evening dress. The answer is the same as for a ball invitation. Invitations to pic-nics, private theatricals, concerts, tea parties and other entertainments, generally state the nature of such entertainment, and are a little less formal than those already given. For a musical party: "Mrs. R-- requests the pleasure of Mr. and Mrs. P---'s company, on Thursday evening, Feb. 10th, at 8 o'clock, to meet the members of the Harmonia Musical Society." And if you have a programme of the concert, enclose it. Or, "Mrs. F--- expects a few friends on Monday evening next, at 8 o'clock, to take part in some dramatic readings, and would be happy to have Miss B--- join the party." Or, "Mrs. S---'s compliments to Miss P---, and would be pleased to have her join a pic-nic party to Pine Grove, on Wednesday, June 14th. Carriages start from Mrs. S---'s at 9 o'clock, and a place will be reserved for Miss P---." Notes of invitation must always be dated, and your address in full written in one corner, thus: "Feb. 6th, 18--. "Miss M---. requests the pleasure of Miss N---'s company to a small evening party, on Friday evening next, at 8 o'clock. "No. 762 R--- Street." The body of the invitation must be in the middle of the sheet, and date a little above to the right, the address a little below to the left. The envelopes containing invitations must be directed always to the private residence of the person invited, never to a place of business or office. When the officers of a regiment or a ship are invited to an entertainment, and it is not possible to invite them all, it is customary to send an invitation to the Colonel or Commander, accompanied by a certain number of blank tickets, if it be a public ball, or by an intimation that the host would be glad to see Colonel or Captain --- and so many of the officers of the regiment or ship. Invitations by a regiment to a ball, to be given by the officers, are worded as follows: "Col. and the officers of the --- Regiment, U. S. A. (or other branch of the service), request the pleasure of Mr. and Mrs. C--- 's company on the 7th of December, at 9 o'clock. "R--- Barracks, corner of --- and --- Streets." Answers should be addressed to the Colonel of the regiment, and worded thus: "Mr. and Mrs. C's compliments to Colonel -- and the officers of the - Regiment, U. S. A., and accept with pleasure their polite invitation for the 7th of December."
