Now add up these, thus: 60 plus 14 plus 14; this gives 88 as your farsight number. Anything over 60 means you can see like a hawk.
Take two boards, cards or papers, each about half a foot square; divide them with black lines into 25 squares each, i.e. 5 each way; get 6 nuts and 4 pebbles, or 6 pennies and 4 beans; or any other set of two things differing in size and shape.
Let the one to be tested turn his back, while the Guide places 3 nuts and 2 pebbles on one of the boards, in any pattern he pleases, except that there must be only one on a square.
Now, let the player see them for 5 seconds by the watch; then cover it up.
From memory, the player must place the other 3 nuts and 2 pebbles on the other board, in exactly the same pattern. Counting one for every one that was right. Note that a piece exactly on the line does not count; but one chiefly in a square is reckoned to be in that square.
Do this 4 times. Then multiply the total result by 5. This gives his quicksight number, to be added to his diveness score.
Can you hear like an owl? An owl can find his prey by hearing after dark. His ears are wonderful. Let us try if yours are.
