temeraire thought it an excellent idea to stay close to the river , in any case ; one grew so very parched , much more quickly than one might have expected , and then of course there was caesar - he cast a disgusted look over : caesar had needed to be carried to the river , even after they had given him two canteens full of water , and told him there was more to be had , even more cool and refreshing ; it had not stirred him to make any effort .
