I cannot sufficiently regret that I was unfortunately
prevented from keeping my engagement to drive with you on
Wednesday. An important telegram, received but a moment
before the time set for our "outing," left me but a brief
five minutes to catch the first train for R----, where
affairs, permitting no delay, awaited my attention.
Dare I hope that I have your pardon for so great a seeming
negligence?
Very respectfully yours,
