       With his wife and mother, he founded Arnold Bakery. They tried new recipes (配方). changing the kind and amount of flour used. This enabled Arnold to work there without too much pain. The bread, made with unbleached flour (标准粉), was baked in a brick oven (烘炉).

观刈麦

田家少闲月，五月人倍忙。

夜来南风起，小麦覆陇黄。

妇姑荷箪食，童稚携壶浆，

相随饷田去，丁壮在南冈。

足蒸暑土气，背灼炎天光，

力尽不知热，但惜夏日长。

复有贫妇人，抱子在其旁，

右手秉遗穗，左臂悬敝筐。

听其相顾言，闻者为悲伤。

家田输税尽，拾此充饥肠。

今我何功德，曾不事农桑。

吏禄三百石，岁晏有余粮。

念此私自愧，尽日不能忘。
