In the Conroy arms, the field is charged with "an ancient book, open, indexed, edged or." This charge represents the honourable and hereditary office of Leanachie bard and herald to the O'Connors, Kings of Connaught. The motto under the coat of arms signifies that "history once written in this book cannot be destroyed by time." It was the privilege of the ancient bard of the tribe "to stand alone with the new-made King upon the sacred mount of Carn Fraoich and there to deliver into his hands the white wand or sceptre of royalty." Mechanical objects follow next--ploughs, harrows (the Harrows bear three harrows), scythes, spades, cartwheels (the latter occur in the arms of Carter and Cartwright). These are all typical of husbandry, and suggest agricultural industry on the part of the original bearers. Chaucer's son-in-law, Sir Payne Roet--derived doubtless, from the French _rouet_, a wheel--bore three wheels on his shield, and in blazoning this coat of arms (Fig. 52), Guillim quotes Pliny's fable of the Roman farmer who was accused to the authorities of being a magician, because his fields were fruitful, whilst those of his neighbour were barren. [Illustration: FIG. 52.] "Wait," said the farmer, "and I will show you my conjuring tools;" and therewith he produced his plough and a cartwheel. From this anecdote we gather that Sir Payne Roet must have been distinguished as an agriculturist. Then come the implements for making clothes as well as some items of dress. Wool-cards are borne by the Cardingtons; shuttles by the Shuttleworths; Sir John Maunsel bears three maunches (sleeves); the Bartlelots, gloves; the Hose family bear stockings; the Arthurs of Ireland three boots, blazoned as "three Irish brogues"; the Huths have a hat (_hut_ being the German for hat). One family of Palmers charges their shield with three palmer's staves; another has a pilgrim's scrip. The Spences bear three penny-pieces, this latter charge symbolizing commerce. Workman's tools--pickaxes, hammers, levels, squares, hatchets, nails, plummets, etc.--had all great heraldic significance. The pickaxe was to remind its bearer "whence he was digged"; the level that his actions must be justified by the rule of reason and justice; the square taught the cultivation of an even judgment; the nails, fixity of purpose; the plummet, prudence in fathoming the problems of life. The objects wrought by these tools follow. First, come works of masonry. One Oldcastle bears a "tower triple-towered"; Sir Edward Mansel, a tower with a scaling ladder against it; whilst three castles occur in the arms of the Scarborough family. The heralds, be it noted, made a great distinction between a tower and a castle, when charging either upon a shield. For, whereas a tower must never occupy the whole of the field, a castle "extendeth itself all over the shield from one side to the other." Three arches are borne by the Archers; the Trowbridges bear a bridge.
