When the machine has acquired a certain speed it leaves the water in exactly the same manner as on the land and immediately increases its speed, due to the released friction from the water. It also has a slight tendency to jump into the air due to the released friction between the boat and water. Once into the air, the operator is the same as with the regular land-equipped Curtiss aeroplanes. The landing is made in the ordinary manner, bearing in mind to keep the boat as near level fore and aft as possible, and if the water be very rough to allow the tail of the machine to settle on the water first. This will prevent any possibility of sticking the front of the boat into an unexpected wave. As should be the case with any aeroplane, it is advisable to start and land against the wind if there be much, but this is not compulsory. The hydro may be landed even while drifting sideways, in an emergency case. It is obvious that to do this with a land machine would be to invite disaster. The writer saw a forcible demonstration of the one and two pontoon types of hydros during the Hydroaeroplane Meet in France, and he had the only machine there with the single pontoon, and also the only one able to go out on rough water. He successfully made flights and landings in waves six to eight feet high, whereas three hydros of the two pontoon type were wrecked in waves less than two feet high. The single pontoon-equipped hydro may be dragged out on the banks any place where a space two feet wide may be obtained, and on my recent trip down the Mississippi, I had occasion to rejoice in this fact and put it to a practical test, as I was hauled out on shores between large rocks or stumps in several instances. The turning of the hydro is accomplished by simply turning the rudder and leaning towards the turn, the same as on a bicycle, allowing the motor to run on reduced or half throttle. The exhilaration of flying a hydro cannot be described on paper. It is the fastest motor boat in the world, and to be able to approach a launch and jump over it and observe the consternation of the passengers is the keenest pleasure imaginable. The hydro may be used solely as a motor boat if desired, at a speed of sixty miles per hour, without a drop of water ever touching its passengers, or if weather be favorable, flights may be made at will of the operator. The surface of a river or lake offers the ideal condition for landing or starting an aeroplane, and these are more numerous than suitable grounds for land machines, besides this the air conditions over water are always better than over land, due to its unbroken surface, which does not obstruct the air currents as do trees, houses, etc., on land. An automatic safeguard exists in the hydro to prevent accidents, such as has caused the loss of lives on land, and that is as follows:
