July 2—Going further into the question of bird-song being a method of recognition as between male and female, I have come across a Willow-warbler: they are distinct species but their general appearance is precisely the same; even the alarm note is said to be the same: but Chiffchaff has a harsh song, consisting of the two syllables which gave him his name, while Willow-warbler has a sweet, little song such às we hear trees when these birds pass through as migrant And the fact remains that the entirely apart and never inter! reminds me of a story told (say, f by R. G. Knowles, one of England's great music-hall artiste: "my brother Bill and I Ji dus by U.S-made Consolidated (PHY-5) These flying boats, which have a 1 span and weigh 27,080 Ib. but are called "sardine tins" by British pilots because of their compactness compared with the monstrous British-built Short Sunderlands, can cruise over 4,000 miles, and one of them set a British record by staying in the air for 24 hours, The Catalinas could fly from the Bismarck to two, Italy has none. However, airfields ashore are "fixed carriers," and they are better than mobile carriers because they are not bound by sea carriers' limitations, and on the continent of Europe the Axis controls most of the fixed carriers.
Therefore, as the Bismarck and Crete demonstrated, British sea-air power becomes progressively effective as it moves away from shore. Two aircraft carriers, the brand-new Victorious and the still unsunk Ark Royal, were able to cripple the most powerful battleship in the world just before it came within danger range of land air bases in France. Conversely, the British did not dare expose vulnerable aircraft carriers, which they call "floating blocks of flats," in the confined waters of the Aegean; and ships without planes consequently took an unmerciful beating.
Torpedoes played a greater part than shellfire in crippling and sinking the Bismarck. At Taranto, at Matapan and in this conflict, the British have shown great skill in using the torpedo-carrying aircraft, which was invented by a U.S. naval officer in 1912, which has surprisingly not been adopted by the Germans in the Battle of the Atlantic. To launch torpedoes the Fleet Air Arm used antique wire-stayed biplanes, which carrier pilots refer to as "string bags.
