The celebrity homemaker said she was touched by the outpouring of support she has received from millions of people who have visited her Web site, according to a letter posted by Stewart on www.marthatalks.com.

Stewart, who reported to Alderson Federal Prison Camp before sunrise last Friday, said life at the camp held few surprises.

"The camp is fine; it is pretty much what I anticipated," she said in her Internet posting.

"The best news - everyone is nice - both the officials and my fellow inmates," the letter continued. "I have adjusted and am very busy. The camp is like an old-fashioned college campus - without the freedom, of course."

In the posting, Stewart noted that any gifts sent to her must be returned to the sender by prison officials. "Instead, if you are so inclined, please make a donation to the American Cancer Society."
