From Chapter 2:
Sir Francis Vere, in the account of his services by sea and land which he wrote about 1606, mentions that on an expedition to the Azores in 1597, the Earl of Essex, waiting for news of the enemy at St. Michael, "called for tobacco ... and so on horseback, with those Noblemen and Gentlemen on foot beside him, took tobacco, whilst I was telling his Lordship of the men I had sent forth, and orders I had given." Presently came the sound of guns, which "made his Lordship cast his pipe from him, and listen to the shooting."

From Chapter 6:
There was clearly no prejudice against smoking at Cambridge. Abraham de la Pryme notes in his diary for the year 1694 that when it was rumoured in May of that year that a certain house opposite one of the colleges was haunted, strange noises being heard in it, several scholars of the college said, "Come, fetch us a good pitcher of ale, and tobacco and pipes, and wee'l sit up and see this spirit." The ale was duly provided, the pipes were lit, and the courageous smokers spent the night in the house, sitting "singing and drinking there till morning," but, alas! they neither saw nor heard anything.
