Airships past and present, together with chapters on the use of balloons in connection with meteorology, photography and the carrier pigeon . FlG. 54.—Kresss flying machine. However, this motor was used in spite of the fact that it wasnearly 4 cwt. heavier than the weight allowed for in the money had been spent, and it was not possible to makegreat alterations at this stage. Kress brought the boat on railsdown to the waters edge, and then very carefully performedcertain evolutions. Gradually his courage increased, he ran themotor a little faster, and found that at 18 horse-power there wasa tendency for the boat to be lifted out of the water. He FLYING MACHINES. 101. reached the end of the lake in 20 minutes, and then proceededto turn back. At this moment the boat swayed first to the leftand then to the right, and as a result of these vibrations it got 102 AIESHIPS PAST AND PEE SENT. into such a position that it was unable to right itself. A gust ofwind added to the difficulty, and there was nothing to be donebut to jump into the water. A man had been deputed to beready with a boat in case of accident.
