"Dear Olga,—You must get F. to take you to dinner on Friday night next. You must go to the Moscow Restaurant, and be there by 7.45 prompt. Please look your handsomest, and spare no pains to be agreeable. When the waiter brings you liqueurs be especially fascinating. Act on the Berlin plan.

"I have been very busy," replied Dick.

"While I have been very lonely."

"Lonely! You lonely, Countess?"
