Blue Bonnet finished her visit with Carita and went back to her room . She opened her desk and getting out an invitation looked it over carefully . At the top of the note-paper reposed a tiny golden lamb , and underneath , the letters A. O. O. L. formed a monogram in blue and gold . A skull and cross-bones had been drawn in ink and a message followed : `` The presence of Miss Blue Bonnet Ashe is demanded at twelve o'clock to-night , February the nineteenth , at number fifteen Fifth Avenue : the said Miss Ashe to appear in a winding sheet , noiseless shoes and a bath-robe . Miss Ashe has the privilege of bringing refreshments with her if inclined ; the committee suggesting that they be in keeping with the shades of night : skeleton salad , ghost sandwiches , assorted spooks or witches ' delight . A roasted hobgoblin will be served soon after the meeting opens . Please be on time , and hold your honorable body in readiness for this or any other sacrifice that may be demanded by the Order .
