What Silver was talking about

what Silver was talking about ‘Well now，Cap’n Smollett，’said Silver，sitting down in the sand，‘you were very clever，last night．One of you is very quick with a knife，isn't he？Some of my men were frightened，and perhaps I was too．Perhaps that's why I'm here now．But you won't do it again，by thunder！We'll drink less rum and watch more carefully．I was asleep，but I almost caught you．The man you knifed wasn't dead when I reached him．’

‘Well？’said Captain Smollett，pretending to understand．But I guessed what Silver was talking about．I remembered Ben Gunn's last words to me．Perhaps he had visited the pirates during the night，when they were lying around their fire，full of rum．

‘We want that treasure，and we'll have it！’said Silver．‘Now，you have a map．Give it to us，and stop killing poor sea-men when they're asleep，and we'll let you choose what to do．Either come aboard ship with us when we have the treasure，and we'll take you to a safe place；or stay here on the island．’
