The cane in these cane-bottom chairs is the bark from a vine. To be pliant and workable, cane needs to be soaked before it can be woven. Cane-bottom chairs are very popular, even to the point where the famous writer William Makepeace Thackeray wrote a poem about them:

But of all the cheap treasures that garnish my nest,

There is one that I love and I cherish the best:

For the finest of couches that's padded with hair

I never would change thee, my cane-bottom'd chair.

The Rose Bowl is an outdoor stadium in Pasadena, California, opened in 1922.  It was originally built as a horse-shoe, but the south end was later added to complete the bowl.

The stadium is the site of the annual college football game – the Rose Bowl – held on New Year's Day. It hosted events during the 1932 and 1984 Olympics, and was the venue for the 1994 FIFA World Cup Final and the 1999 FIFA Women's World Cup Final.

Page 123. " Mrs Dubose was a morphine addict,' said Atticus. 'She took it as a painkiller for years. "

Morphine is a narcotic that affects the central nervous system. Besides relieving pain, morphine impairs mental and physical performance, relieves fear and anxiety, and induces euphoria. Morphine's euphoric effects can be highly addictive. Tolerance (the need for higher and higher doses to achieve the same effect) and physical and psychological dependence quickly develop.

Withdrawal from morphine addiction causes nausea, chills and sweats, lasting up to three days.
