what is the purpose of paragraph 5?

This is our introduction to Elisa.

"Elisa watched them for a moment and then went back to her work. She was thirty-five. Her face was lean and strong and her eyes were as clear as water. Her figure looked blocked and heavy in her gardening costume, a man's black hat pulled low down over her eyes, clod-hopper shoes, a figured print dress almost completely covered by a big corduroy apron with four big pockets to hold the snips, the trowel and scratcher, the seeds and the knife she worked with. She wore heavy leather gloves to protect her hands while she worked."
