Hawthorne Works是一个专有名词，一个工厂群的名字：

下面资料来自wikipedia：

The Hawthorne Works, in Cicero, Illinois, was a large factory complex built by Western Electric starting in 1905 and operating until 1983. It had 45,000 employees at the height of its operations. Besides telephone equipment, the factory produced a wide variety of consumer products, including refrigerators and electric fans. Hawthorne Works was named for Hawthorne, Illinois, a small town that was later incorporated into Cicero. The facility was so expansive, it contained a private railroad to move shipments through the plant to the nearby Burlington Northern Railroad freight depot. Workers regularly used bicycles for transit within the plant. It was demolished in the mid-1980s and replaced with a shopping center. One of the original towers remained at the corner of 22nd Street and Cicero Ave.
