Looking at Mars had put Hooke in mind of cœlestial affairs; for that reason he set out with Daniel one morning in a wagon, with a chest of equipment. This must have been important, because Hooke packed it himself, and wouldn't let anyone else near it. Wilkins kept trying to persuade them to use the giant wheel, instead of borrowing one of John Comstock's wagons (and further wearing out their welcome). Wilkins claimed that the giant wheel, propelled by the youthful and vigorous Daniel Waterhouse, could (in theory) traverse fields, bogs, and reasonably shallow bodies of water with equal ease, so they could simply travel in a perfectly straight line to their destination, instead of having to follow roads. Hooke declined, and chose the wagon.
