To quickly assess the difficulty of the text, read a short excerpt:
The aero- plane now, does not have to be pushed up so steep an incline as before. With its load it has only to be glided upward in the air half so liigh in a giyen time, and decends only half so far in that time. For this reason it will sustain double the load with the former power, and in regard to the sec- ond case of modifying the aeroplane, you double its area and lift it at its former incline. This doubled area calls tor double the horizontal pressure, to move the ship at its former rate c...arrying double the load, because of the incline of the aeroplane not having been changed, and was compelled to glide upward in the air at as steep an angle as before any modifications were made and at the former rate. Or we can ilkistrate the case equally clare by saying, the aeroplane crowded the air downward, and this doubled horizontal pressure was then secured by multiplying the area of the blades of the screw to eight fold. Now the explanation of the modified areas etc. , of the screw blades of the air- ship using horizontal screws, explains the philosophy of those on the ships using aeroplanes.
