_January 10._--Took my old accumulator to electrician. To my great pleasure he said there was nothing wrong, only wanted filling and charging. _January 11._--Tried my acc. on the train, running through switchboard; a great success. Engine runs very well. All switchboard connections absolutely correct; the reading when running: volts 3.5 to 4.25, amps. 1 to 2.5. _January 12._--To Bassett Lowke's and bought wagon; yellow colour, red lettering; splendid model. _January 13._--At matinee _Orpheus in the Underground_, at His Majesty's. Exceedingly good show. Courtice Pounds, L. Mackinder and Lottie Venn--all first rate; good voices and not afraid to use them. _January 15._--To Hippodrome. The feature two amazingly clever Chimpanzees. Leo Fall's _Eternal Waltz_ a pretty operetta. _January 16._--Final golf match between Dad and myself. Dad wins match and rubber by 1 up. _January 17._--Got back my P.O. bank book. Total now L6 3s. Discovered slight leakage at joint between the cylinder and combustion head of the gas engine, owing to wearing away of asbestos washer, so causing a very small but appreciable diminution of compression. Made a temporary stopping with vaseline. Evening.--Dad and I to _Tales of Hoffmann_, at the Opera House. This time a magnificent performance. _January 19._--Dynamo arrived. A beautiful machine. _January 20._--Went with Dad to International football match, England _v._ Wales, at Twickenham. Score--England, 8 points; Wales, _nil_. A splendid game. Wales beaten chiefly owing to their very poor three-quarters. Little to choose between the packs. _January 31._--Having re-started music with a good teacher, a pupil of Professor Hambourg, I have practised very hard on the piano these last few days. In his enthusiasm for engineering he devoured books like "Engineering Wonders of the World," "How it Works," "How it is Made," "Engineering of To-day," "Mechanical Inventions of To-day"; also books on wireless telegraphy and aviation. A great lover of books, he liked on off-days to visit London bookshops and rummage their shelves. Very proud he was of his purchases during these excursions. From time to time he would have a run round the museums and picture galleries of London or take a trip to Hampton Court--Wolsey's palace and William III's home--a spot dear to him for its links with history and for the beauty of its surroundings. He was always enthralled at the British Museum by the Rosetta Stone--that key by means of which Champollion unlocked for the modern world the long-hidden secret of Egypt's ancient civilisation.
