As one works with color in a practical, or experimental way, one is impressed by two apparently unrelated facts. Color as seen is a mobile, changeable thing (1) to a large extent on the relationship of the color (2) other colors (3) simultaneously. It is not (4) in its relation to the direct stimulus which (5) it. On the other hand, the properties of suces that give (6) to color do not seem to change greatly under a wide variety of illumination color, usually (but not always) looking much the same in artificial light as in daylight. Both of these effects seem to be (7) in large part to the mechanism of color (8) .

When the eye is (9) to a colored area, there is an immediate readjustment of the (10) of the eye to color in and around the area (11) . This readjustment does not promptly affect the color seen but usually does affect the next area to which the (12) is shifted. The longer the time of viewing, the higher the (13) , and the larger the area, the greater the effect will be (14) its persistence in the (15) viewing situation. As indicated by the work of Wright and Schouten, it appears that, at (16) for a first approximation, full adaptation takes place over (17) time if the adapting source is moderately bright and the eye has been in (18) darkness just previously. Also, (19) of the persistence of the effect if the eye is shifted around from one object to another, all of which are at similar brightness or have similar colors, the adaptation will tend to become (20) over the whole eye.

You really have to get very old before you realize you’re old. I’m in my middle fifties and l don’t feel (21) yet. However, sometimes I look back at my childhood and (22) things to the way life is for (23) kids, some things have certainly changed.

One area of change is (24) . Some changes have been improvements. Some changes, on the other hand, have been (25) .

When I started school, most people didn’t have a television; TV was just beginning to get (26) . My father decided to go all out and buy a 16-inch black and white Motorola (27) . I still remember watching the Lone Ranger save people from the (28) guys on that awesome electronic machine. That was exciting!

Now, (29) have larger pictures in full color. The pictures are clearer and the sound is much more (30) . The new high definition sets are made to rival (31) screens.

The variety and quantity of programming has (32) greatly. There are hundreds of channels "and more shows than one person could ever watch. There are many fine entertainment and educational (33) . There’s also a lot of garbage, stuff that most (34) don’t want their kids exposed to. Overall, we have more choices, and that is good.

I wonder what (35) will be like when today’s kids are my age.

The lake lay before me, blue and peaceful, in the evening (36) . On either side the mountains rose sharply surrounding it in a kind of bowl. A few sheep (37) their sides here and there and a cow was (38) with eating on the lower slopes. The place was so far away, so untouched by human work that it seemed the very place to (39) . Even Higgs, I thought, won’t be able to find me here.

I sat down by the edge of the lake, and pulled (40) my shoes and socks, put my (41) in the water. It was cold, like ice. After a moment I (42) over and spread some of the (43) on my hot face. I could see myself faintly in the water staring at me like a (44) .

I realized suddenly how (45) I was of running away. Surely, I thought I could live here for a few days, out of (46) of Higgs and his men. While I tried to (47) some plans for the future, I found a tiny cottage on the far side of the (48) with some smoke coming from its roof. I still had a little money. Perhaps they would give me a (49) and some food.

As I watched, a man came out of the house and down to a little (50) at the lakeside. He got into it and began to move (51) towards my side. I could not see his (52) at first. He continued calmly (53) the lake, and when he was about halfway, he rested his oars and the boat drifted into a patch of sunlight. He (54) a hand in a friendly way of greeting. I Was about to raise mine, (55) all at once, I saw his face clearly, it was Higgs!
