Under the Commonwealth he was not only mayor, but a great Presbyterian luminary. He harangued and expounded Revelation always in favour of the Commonwealth and Presbyterianism, and against the Crown and the Mitre. But no sooner did Charles II. land than he swung completely round. All his political and religious views changed, and he declared that the great horn was Old Noll and the little horn was Dickon. By this means Nicholas Tyack secured his position, and remained mayor of Saltash. He had been high-handed in his proceedings before; he became more high-handed under the Restoration. He wanted to apprentice his son in London; so he took the youth to town, lived well whilst there, and on his return charged the expenses to the town. Nicholas had a great advantage in living next door to the Town Hall, for he was able to break a way into it through the intervening wall. According to custom and rule, when a meeting of the Town Council was convened, the Town Hall bell had to be rung; but there was no specification as to the _hour_ at which a meeting was to be held, nor was it laid down in black and white that the Hall door was to be unlocked for the occasion. Now when Nicholas Tyack desired to pass his accounts, or to transfer some bit of Corporation land to himself, or legitimatise any other little game to his advantage and the detriment of the public, he rang the bell at night, kept the Hall door locked, and admitted his adherents through his private door, held the meeting in the council-chamber, and passed his accounts and resolutions _nem. con._ But now both the Town Hall and Tyack's house have been swept away. The latter had a fine mullioned and many-light window. The house went first; then the Guildhall. [Illustration: IN SALTASH] The story of the borough of Esh, Esc, or Saltash is specially interesting, as it affords us a precious glimpse into the history of the origin and growth of our municipal towns. Esh, that is to say, _water_, was so-called because situated on the tidal estuary of the united Tamar and Tavy, which junction bears the name of the Hamoaze (Hem-uisg), the border water between Devon and Cornwall, between the English and the British tongues. Here by the water-side settled some serfs, or "natives in stock," of the Baron de Valletort. "Natives of stock were the purest and most absolute bondmen. They were entirely subject to the will of their lord, and were subject to being placed in any tenement in which he might think fit to place them; and were compelled to do for him any work he might call upon them to do; and to pay a sort of capitation tax if they were allowed to be employed elsewhere."[13]
