Grandfather stayed silent until we approached a limping man dressed in dark rags, pushing a cart.

"Wonder where that fellow’s going?" he said. "Looks like he belongs on the waterfront."

A thin white arm flopped over the side of the cart as it jostled over the cobblestones.

"Hullo, there, good man!" called Grandfather. "There is no place for the dead up here. Hullo!" The man ignored us and pressed on steadily.

Nonfiction: The Summer of the Pestilence

For the dead—it is becoming a matter of great difficulty to procure coffins in which to bury them. Should any thing like the same proportion die from among those now sick which have died hitherto, I fear we shall be driven to the necessity of burying in pits, as has been done in New Orleans, and as was done during the great plague in London.

Explanation:

The first excerpt is found in Chapter Eight titled "September 2nd, 1973" from Fever 1793 by Laurie Halse Anderson is based on the yellow fever epidemic that ravaged Philadelphia. The story is from the point of view of the young Mattie Cook, describing how the pandemic had destroyed the lives of the people.

The second excerpt is from The Summer of the Pestilence by George Dodd Armstrong. The book also deals with the history of the same yellow fever that not only affected Philadelphia but also other parts of the nation such as Virginia.

While both books deal with the same pandemic, their dealing with the issue of unprecedented deaths differ a bit. The first book uses a dialogue-conversation approach, with the characters greatly involved whereas the second book uses the first person point of view to address the deaths. These two books may deal with the same issue but their approaches of the deaths and sick people differ such that their narrative plots also differ.
