Read it through once

“Look ’ere, guv’nor, there ain’t no sense in me a-keepin’ you ’ere. I may find Sam soon, or I mayn’t; but anyhow he ain’t like to be in a way to tell ye much to-night. Sam is a rare one when he starts on the booze. If you can give me a envelope with a stamp on it, and put yer address on it, I’ll find out where Sam is to be found and post it ye to-night. But ye’d better be up arter ’im soon in the mornin’, or maybe ye won’t ketch ’im; for Sam gets off main early, never mind the booze the night afore.”
