| Title | Letter from Henry Bradwardine Jackson, Admiralty, to Dugald Clerk |
| Date | 21 December 1914 |
| Description | Encloses a note he has put forward on the subject of creeping mines. Bidder and Borley have remarked that moorings must be light; and that water pressure on a spherical mine will be less than Jackson's value. Long mooring ropes will be required to allow the mines to bump against ships. |
