apprehension of important political changes, which eventually took place
by the resignation of Mr. Addington a short time afterwards, caused some
embarrassment in the measures and proceedings of the Administration.
After all was ready at Portsmouth for the embarkation, and part of the
troops destined for the service were actually on board, the expedition
was suddenly countermanded; and the question, whether it should finally
proceed to Africa or not, was reserved for the decision of Lord Camden,
who shortly afterwards succeeded to Lord Hobart in the Colonial
department.

In consequence of this change, Park was informed at the Colonial Office,
that the expedition could not possibly sail before September; and it was
suggested to him by some person in authority, that he might employ the
interval with great advantage in improving himself in the practice of
taking astronomical observations, and in acquiring some knowledge of the
Arabic language. He was at the same time informed, that any reasonable
expence which he might incur in acquiring this instruction would be
reimbursed to him by Government. In consequence of this intimation, he
engaged a native of Mogadore, named Sidi Omback Boubi, then residing in
London, who had served as the interpreter of Elphi Bey, (the ambassador
of the Mamelukes from Cairo) to accompany him to Scotland, for the
purpose of instructing him in Arabic. They immediately left London
together, and arrived early in March at Peebles; where Park continued to
reside together with his African instructor, till about the middle of
May. He then finally quitted his house at Peebles, and took his family
to the farm at Fowlshiels, where he quietly waited the expected summons
of the Secretary of State. During all this time he employed himself with
great diligence in acquiring a familiar use of astronomical instruments,
and in the study of the Arabic language, in which he became a tolerable
proficient.
