Rowing, then, is out of the question for a bird which is to move at a speed far greater than that of any boat.
How, then, is horizontal movement gained .' To understand this a knowledge of the parallelogram of forces is necessary. The proof of the principle involved will be found in any book on elementary mechanics.
I shall merely try to make clear what is meant. If two forces act upon a body at one point, they combine to make one force. If B A and C A are two forces i82 THE STRUCTURE AND LIFE ...OF BIRDS chap.

If, now, we start with a force represented by DA, we can do in imagi- nation, what often happens in reality, break, it up into two forces BA and CA, or other forces acting along two other lines, which must, however, con- FlG. 49.
