From Chapter 1:
Another place making a similar claim is Hemstridge, on the Somerset and Dorset border. Just before reaching Hemstridge from Milborne Port, at the cross-roads, there is a public-house called the Virginia Inn. There, it is said, according to Mr. Edward Hutton, in his "Highways and Byways in Somerset," "Sir Walter Raleigh smoked his first pipe of tobacco, and, being discovered by his servant, was drenched with a bucket of water."

From Chapter 5:
When excavations were in progress early in 1901, preparatory to the construction of Kingsway and Aldwych, they included the removal of bodies from the burying-grounds of St. Clement Danes and St. Mary-le-Strand; and among the bones were found a couple of the curious tobacco-pipes called "plague-pipes," because they are supposed to have been used as a protection against infection by those whose office it was to bury the dead. These pipes have been dug up from time to time in numbers so large that one antiquary, Mr. H. Syer Cuming, has ventured to infer that "almost every person who ventured from home invoked the protection of tobacco."
