what did montomercy do at sonning?

Montmorency caught a river-rat for dinner and offered it to the men as a gift while at Sonning.

"I forget the other ingredients, but I know nothing was wasted ; and I remember that, towards the end, Montmorency, who had evinced great interest in the proceedings throughout, strolled away with an earnest and thoughtful air, reappearing, a few minutes afterwards, with a dead water-rat in his mouth, which he evidently wished to present as his contribution to the dinner: whether in a sarcastic spirit, or with a genuine desire to assist, I cannot say."
