A long Sunday walk was always a feature of Mr. Dodgson's life in the
vacations. In earlier years the late Mr. W. Watson was his usual
companion at Guildford. The two men were in some respects very much
alike; a peculiar gentleness of character, a winning charm of manner
which no one could resist, distinguished them both. After Mr. Watson's
death his companion was usually one of the following Guildford
clergymen: the Rev. J.H. Robson, LL.D., the Rev. H.R. Ware, and the
Rev. A. Kingston.

On the 26th Mr. Dodgson paid a visit to the Girls' High School, to
show the pupils some mathematical puzzles, and to teach the elder ones
his "Memoria Technica." On the 28th he returned to Oxford, so as to be
up in time for term.

I have said that he always refused invitations to dinner; accordingly
his friends who knew of this peculiarity, and wished to secure him for
a special evening, dared not actually invite him, but wrote him little
notes stating that on such and such days they would be dining at home.
Thus there is an entry in his Journal for February 10th:

"Dined with Mrs. G--(She had not sent an
'invitation'--only 'information')."

His system of symbolic logic enabled him to work out the most complex
problems with absolute certainty in a surprisingly short time. Thus he
wrote on the 15th: "Made a splendid logic-problem, about
"great-grandsons" (modelled on one by De Morgan). My method of
solution is quite new, and I greatly doubt if any one will solve the
Problem. I have sent it to Cook Wilson."
