Summary:

Asks for the reference in which JP states that some erratic boulders came from a lower to a higher level. CD is writing a paper ["Transportal of erratic boulders", Collected papers 1: 218–26] in which he believes he has the true explanation. Would like as many instances, with details, as possible.
