Further on, the Earl takes blame to himself for not having seen how he might have added to the prosperity of the Manx folks by turning the island to more profitable account, “for he who is not careful of what he has, is not worthy to possess it.” He advises that manufactories and more trade be established in Man. “Then the sea will be covered with ships, and the land with inhabitants, to the great advantage of the whole country.” He further gives excellent advice as to the selection of a bishop for the island. He must be one, he says, who is a pious and worthy person, seeing that the clergy do their duty, and therefore one who must reside in the island, and have no benefice elsewhere. Further, the Earl would have a university, which, from the great natural advantages of the island, might be maintained at moderate cost and be serviceable to many, “finishing by putting something into the purse of its suzerain lord. But of this I will talk with you more, if it please God that I see you again, and have a quiet mind.” He adds more good counsel for personal conduct, and for the general business of life. This work was never finished, as the Earl intended it, but is published as he left it in Peck’s _Desiderata Curiosa_.[21] Footnote 21: Vol. ii. lib. ii. In September of 1647 Parliament at last definitely made allowance for the maintenance of the Earl’s children. It was one-fifth of his revenue, the same as they meted to the rest of the “delinquents.” The allowance was made upon Knowsley, and thither two of the Earl’s three daughters, Catherine and Mary, were at once sent. Lord Fairfax issued orders that Major Jackson, who had established himself with his family in the mansion, should clear out, and the guardians were further enjoined to see “that the said Major Jackson” did no damage to house or park before he went. Lady Derby writes from London, 14th March 1648: “I am advised to go to Lancashire, and live there on the little which has been allowed to my children; for I receive nothing; and I hope that I may be able to make it go further if I am on the spot. One must live economically, and make the best of what one has.”
