To John Phillips   14 February [1848]

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.

To John Phillips   7 March [1848]

Summary

JP’s reference was clear, but seems to be different from the case cited by W. Hopkins about erratic conglomerate boulders. Asks for more details on the latter. CD does not think much of Hopkins’ paper ["Elevation and denudation of the district of the lakes of Cumberland and Westmorland", Q. J. Geol. Soc. Lond. 4 (1848): 70–98].

To John Phillips   [12? March 1848]

Summary

Thanks JP for his note and reference. CD’s paper will not deal with the general question of erratics but only their transportal from a lower to a higher level ["The transportal of erratic boulders", Collected papers 1: 218–27]. His notion is that the boulders were transported by coast-ice, not drifting icebergs, and that during the period of transportal the land was subsiding. Can JP tell him whether the raised conglomerate boulders he observed were rounded or angular?

To John Phillips   [7 or 14 April 1848]

Summary

Some geologists (especially H. T. De la Beche) doubt boulders have really been carried above their parent rock, but rather thought they were left behind as a result of denudation. Asks JP’s view of this, which he can quote. Supposes he will be well abused for his paper, but is resolved "not to show a white feather".
