The king gave a letter of patent to Archibald Napier, apparent of Merchiston, for an invention of his, a ‘new order of gooding and manuring of field-land with common salt, whereby the same may bring forth in more abundance, both of grass and corn of all sorts, and far cheaper than by the common way of dunging used heretofore in Scotland.’ That nothing came of this plan need not be told.
1598.
The Merchiston Napiers must have been a theme of some curiosity and no little remark at this time, seeing that three generations were now living, all of them busy-brained, ingenious, and original-minded persons. First was the laird himself, master-general of the cunyie-house, still in the vigour of life, being not more than sixty-five years of age. Second was John Napier, the fiar or heir, only sixteen years the junior of his father, constantly engaged in puzzling out profound problems in mathematics and prophecies in the Apocalypse. Finally, this grandson of the laird, a youth of four-and-twenty, and already, as we see, exhibiting the active intellect of the family.
Archibald became a favourite courtier of James VI. and Charles I., by the latter of whom he was raised to the peerage. He joined the anti-covenanting party, and endured some adversity in his latter days.
The carboniferous formation, as is well known, does not extend in Scotland beyond the Ochils; but in the remote county of Sutherland, on the coast at Brora, there is a patch of oolite, in the lower section of which is a workable bed of coal, between three and four feet thick. John, tenth Earl of Sutherland, had discovered this valuable deposit, but being cut off by poison (anno 1567), he had no opportunity of trying to turn it to advantage. The Sutherland estates were now under the management of a woman of some force of character, and who has by accident a place in our national history—Lady Jean Gordon. Being divorced by Bothwell, in order to admit of his marriage to Queen Mary, she had subsequently married one Earl of Sutherland, and become the mother of another, for whom she was now acting. By this clever countess the coal of Brora was for the first time worked, not merely for its use in domestic purposes, but as a means of establishing a salt-work. Some pans being erected by her ‘a little by-west the entry of the river,’ there was good salt made there, ‘which served not only Sutherland and the neighbouring provinces, but also was transported into England and elsewhere.’ This was a good effort, but, like all similar enterprises in that rude age, it met with interruptions. One vigorous renewed effort was made by the countess’s son, Earl John, in 1614. It was not, however, till our own time, when the first Duke of Sutherland spent £16,000 on the coal-works, and £2337 on the salt-works, that the original designs of Countess Jean could be said to be fully realised. The works are stated to have given forth twenty thousand tons of coal between the years 1814 and 1826.[237]
