BIOGRAPHICAL SKETCHES. 179
entered into some years before, respecting the religious and moral improvement
of the Highlands and Islands of Scotland, appointed Dr. Walker to undertake a
mission to these remote, parts of the country. This he readily undertook, and
performed his arduous task to the entire satisfaction of the Assembly. He was
also authorised by the Commissioners for the Annexed Estates to inquire into
the natural history and productions-the population-agriculture-and the fisheries
of the Highlands and Hebrides. In prosecution of .these important
inquiries, he performed in all six journeys ; and, from the mass of useful information
collected, a posthumous work, entitled “An Economical History of the
Hebrides,” was published in 1808.
Not long after his first mission to the Highlands, which tended materially
to confirm .the high opinion entertained of his character, Dr. Walker was presented
by the Earl of Hopetoun to the church of Moffat, in the Presbytery of
Lochmaben, and county of Dumfries. In this extensive parish a new and inviting
field presented itself for exploring the vegetable kingdom of nature ; and it
is probable that the frequency of his botanising excursions-the utility or
propriety of which were not appreciated by his parishioners-procured for him
the title of “the mad minister of Mofat.” There was another prominent trait in
the demeanour of the Doctor, which no doubt had its due weight in countenancing
such an extraordinary soubriquet. This was an extreme degree of nicety in the,
arrangement of his dress, especially in the adjustment of his hair, which it is
said occupied the village tonsor nearly a couple of hours every day.
It is told of the Doctor, that travelling on one occasion from Moffat to the
residence of his friend, Sir James Clerk of Pennicuik, he stopped at a country
barber’s on the way to have his hair dressed. He was personally unknown to
Strap, although the latter had often heard of him. The barber did all in his
power to give satisfaction to his customer ; but in vain he curled and uncurled,
according to the Doctor’s directions, for nearly three hours. At length, fairly
worn out of patience, he exclaimed-(6 In all my life, I have never heard of a
man so difficult to please, except ‘ the mad minister of Mofat.’” This scrupulous
attention to his hair he continued to observe until advancing years compelled
him to adopt a wig.
The Doctor himself used to mention that he was one day walking in a gentleman’s
park, where he had been collecting insects, with the handles of an insect
net projecting from his pocket. Two ladies were walking near, and he heard
one of them say-“ No wonder the Doctor has his hair so finely frizzled, for he
carries his curling tongs with him.”
On the death of Dr. Ramsay, Professor of Natural History in the University
of Edinbursh, in 1778, Dr. Walker made application to the Crown for the
vacant chair. In this he was successful, and obtained his commission in 1779.
At that period no direct judgment of the General Assembly stood recorded
with respect to pluralities, but the parishioners of Moffat were alarmed at the
circumstance of their minister’s appointment to the professorship, justly conceiving
that, distant as they were from Edinburgh upwards of sfty mileu, & waa
