Then and there we should have tried the thing out, for he was effervescing with fight, but fortunately I was rescued from an odious situation. A policeman was beside us, his notebook in his hand.	Nous allions, séance tenante, vider l’affaire, car il bouillait du désir de se battre, sans l’opportune intervention d’un policeman, qui mit fin à cette ridicule scène en se plantant devant nous, armé de son calepin.

"By George, young fellah, you've put your hand on it!" said Lord John, clapping me on the back. "How we never came to think of it before I can't imagine! There's not more than an hour of daylight left, but if you take your notebook you may be able to get some rough sketch of the place. If we put these three ammunition cases under the branch, I will soon hoist you on to it."

— By George ! mon garçon, vous avez trouvé le joint ! ajouta lord Roxton, en me tapant dans le dos. Comment n’y avons-nous pas songé plus tôt ? C’est inconcevable. Nous n’avons plus guère devant nous qu’une heure de lumière. Cela suffit pour que vous nous rapportiez de là-haut, sur votre calepin, un vague tracé d’ensemble. Approchons de l’arbre ces trois caisses de munitions ; je me charge de vous hisser ensuite jusqu’à la première branche.
