Once I had a boy who worked experimentally with Tinkertoys in his free time. His constructions filled a shelf in the art classroom and a good part of his bedroom at home. I was delighted at the presence of such a student. Here was an exceptionally creative mind at work. His presence meant that I had an unexpected teaching assistant in class whose creativity would infect(感染) other students.

Encouraging this kind of thinking has a downside. I ran the risk of losing those students who had a different style of thinking. Without fail one would declare, " But I'm just not creative."

"Do you dream at night when you're asleep?"

"Oh, sure."

"So tell me one of your most interesting dreams." The student would tell something wildly imaginative. Flying in the sky or in a time machine or growing three heads. "That's pretty creative. Who does that for you?"

"Nobody. I do it."

A new collection of photos brings an unsuccessful Antarctic voyage back to life.

Frank Hurley's pictures would be outstanding----undoubtedly first-rate photo-journalism---if they had been made last week. In fact, they were shot from 1914 through 1916, most of them after a disastrous shipwreck(海滩), by a cameraman who had no reasonable expectation of survival. Many of the images were stored in an ice chest, under freezing water, in the damaged wooden ship.

The ship was the Endurance, a small, tight, Norwegian-built three-master that was intended to take Sir Ernest Shackleton and a small crew of seamen and scientists, 27 men in all, to the southernmost shore of Antarctica's Weddell Sea. From that point Shackleton wanted to force a passage by dog sled(雪橇) across the continent. The journey was intended to achieve more than what Captain Robert Falcon Scott had done. Captain Scott had reached the South Pole early in 1912 but had died with his
