_Artificial Drainage._--Can any of your correspondents refer me to a work, or works, giving a history of draining marshes by machines for raising the water to a higher level? Windmills, I suppose, were the first machines so used, but neither Beckmann nor Dugdale informs us when first used. I have found one mentioned in a conveyance dated 1642, but they were much earlier. Any information on the history of the drainage of the marshes near Great Yarmouth, of which Dugdale gives passing notice only, would also be very acceptable to me. E. G. R. _Storms at the Death of great Men._--Your correspondent at Vol. vi., p. 531., mentions "the storms which have been noticed to take place at the time of the death of many great men known to our history." A list of these would be curious. With a passing reference to the familiar instance of the Crucifixion, as connected with all history, we may note, as more strictly belonging to the class, those storms that occurred at the deaths of "The Great Marquis" of Montrose, 21st May, 1650; Cromwell, 3rd September, 1658; Elizabeth Gaunt, who was burnt 23rd October, 1685, and holds her reputation as the last female who suffered death for a political offence in England; and Napoleon, 5th May, 1821; as well as that which solemnised {494} the burial of Sir Walter Scott, 26th September, 1832. W. T. M. Hong Kong. _Motto or Wylcotes' Brass._--In the brass of Sir John Wylcotes, Great Tew Church, Oxfordshire, the following motto occurs: "IN . ON . IS . AL." I shall feel obliged if any one of your numerous correspondents will enlighten my ignorance by explaining it to me. W. B. D. Lynn. _"Trail through the leaden sky," &c._-- "Trail through the leaden sky their bannerets of fire." Where is this line to be found, as applied to the spirits of the storm? R. C. WARDE. Kidderminster. _Lord Audley's Attendants at Poictiers._--According to the French historian Froissart, four knights or esquires, whose names he does not supply, attended the brave Lord Audley at the memorable battle of Poictiers, who, some English historians say, were Sir John Delves of Doddington, Sir Thomas Dutton of Dutton, Sir Robert Fowlehurst of Crewe (all these places being in Cheshire), and Sir John Hawkstone of Wrinehill in Staffordshire; whilst others name Sir James de Mackworth of Mackworth in Derbyshire, and Sir Richard de Tunstall _alias_ Sneyde of Tunstall in Staffordshire, as _two of such knights or esquires_. The accuracy of Froissart as an historian has never been questioned; and as he expressly names only _four_ attendants on Lord Audley at the battle of Poictiers, it is extremely desirable it should be ascertained if possible which of the six above-named knights really were the companions of Lord Audley Froissart alludes to; and probably some of your learned correspondents may be able to clear up the doubts on the point raised by our historians.
