[Illustration: 'Jullanar'--midship section.]
Mr. Hunt, publisher of 'Hunt's Yachting Magazine,' has kindly supplied the following measurements of the 'Jullanar,' which were given to him by Mr. Bentall himself, when he would not let anyone else have them. Coming therefore from the fountain-head they are accurate, and should be preserved as a register of detail.

To my mind the genius, daring, and originality of mind of Mr. Bentall were even more fully displayed in the design of the unsuccessful 'Evolution' than of the successful 'Jullanar.'

The 'Evolution,' as her name implied, was the logical outcome of the then tonnage rule, and of the laws of resistance rediscovered, or at least popularised, by Froude. It seems self-evident now that with a belief in these laws only one type of boat could be the result; but Mr. Froude alone had the courage of his opinions, and built the extraordinary 10-tonner which, if it did nothing else, scared the authorities into changing the tonnage rule. 'Evolution' was by far the longest of the 10-tonners, her dimensions being 51 ft. × 6 ft. 6 in.--indeed about the same water-line length as the twenties. To get moderate wet surface the ends were cut away; but as 'Jullanar' already represented the utmost that could be done in that direction, while preserving a fair line of keel, this was cast aside in 'Evolution,' and the profile was that of a true 'fin' boat. More than this, it was found after a trial sail or two that she was very deficient in stability when the lead slab forming the keel was recast in the form of a bulb on the bottom of the plate, the completed design simply forming one of our modern bulb fin keels, but of course, owing to the 94 rule, with vastly less beam. 'Evolution' was not a success because of her insufficient stability, but with the meagre data in possession of the designer as to the stability of boats of this class, it would have been marvellous had the difficulty been overcome in a first trial. To those able to see the beauties in a design, it matters less whether the ultimate outcome has been successful or not, and while to 'the general' nothing succeeds like success, a few have a kindly sympathy and hearty admiration for those who have laboured, that _we_ may enjoy the increase. Many of the best and kindest thoughts and brightest ideas never reach fruition in this world, and so in the mechanical arts there is often more genius displayed in a failure than in a success, with this difference, that a mechanical idea seldom dies, but, 'blossoming in the dust' of one brain, is plucked and worn by another. 'Evolution' lay dead for fifteen years. She has had a striking resurrection on both sides of the Atlantic.
