The question PB was mentioning to WW yesterday, concerned the relative propelling powers of the paddles of a steam vessel according to their position. PB's son has produced a paper which 'endeavours to show that the lower or vertical paddle is the least effective whereas the general impression is that it is the most effective'. PB wants WW to look over the solution which he gives, and see if he can spot any errors.
