from Things To See In Springtime
1. Have you got wise fingers like a blind man?
Put 10 nickels, 10 coppers and 10 dimes in a hat or in one hand if you like. Then, while blindfolded, separate them into three separate piles, all of each kind in a separate pile, within 2 minutes. If it takes you the full 2 minutes (120 seconds), you are slow, and your feel number is 0. If you do it without a mistake in 1 minute and 20 seconds, your feel number is 40, one point for each second you are less than 2 minutes. But you must take off 3 points for every one wrongly placed, so 3 wrongly placed would reduce your 40 to 31. I have known some little boys on the East Side of New York to do it in 50 seconds without a mistake, so their feel-number by coins was 70. That is, 120 seconds minus 50 seconds equals 70. This is the best so far.
2. Now get a quart of corn or beans. Then when blindfolded, and using but one hand, lay out the corn or beans in "threes"; that is, three at a time laid on the table for 2 minutes. The Guide may move the piles aside as they are made. Then stop and count all that are exactly three in a pile (those with more or less do not count at all). If there are 40 piles with 3 in each, 40 is your number, by corn.
3. The last test is: Can you lace your shoes in the dark, or blind-folded, finishing with a neat double bow knot?
Arrange it so your two shoes together have a total of at least 20 holes or hooks to be used in the test, i. e., which do not have the lace in them when you begin. Allow 1 point for each hole or hook, i. e., 20 points, finish the lacing in 2 minutes, in any case stop when the 2 minutes is up; then take off 2 points for each one that is wrongly laced, or not laced. Thus: Supposing 4 are wrong, take off 4 times 2 from 20, and your blindfold lacing number is 12; if the number wrong was 10 or more, your lacing number is 0; if you had 3 wrong, your number is 14.
Suppose by these three tests—coins, corn, and laces—you scored 40, 30, and 14; add these together and they give your feel number; 84.
