  <dc:title>Letter from Henry Bradwardine Jackson, Admiralty, to Dugald Clerk</dc:title>
  <dc: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.</dc:description>
