Logan had ere this time married, and settled himself in Pennsylvania. He prudently continued to devote his attention to commerce, as well as to the public affairs of the colony, and attained to eminent wealth as well as to the highest station. As his years and infirmities increased he partially withdrew from public affairs, and in a residence in the suburbs of Philadelphia devoted his declining years to literature and science. The last office he continued to hold was that of “Chief Justice of the Province of Pennsylvania,” at a salary of 100_l._ per annum. In 1736 he speaks of having already been obliged for five years past to mount the bench on crutches. He desired to retire, but the government could not find a satisfactory successor to his office. During his period of retirement Logan corresponded with his friends in Europe upon metaphysical subjects, and made communications on natural phenomena to the Royal Society, in letters addressed to Sir Hans Sloane, Peter Collinson, and others. He also employed himself in collecting a library--then not an easy task in that part of the world--and having built a room for its preservation, and endowed it with £35 per annum for a librarian, he left the whole to the city of Philadelphia. The Loganian library still exists, but in combination with two other public libraries. The founder is also perpetuated in one of the public squares of Philadelphia, which bears his name. He died on 31st October, 1751. Among the founders of Pennsylvania, Logan ought to be had in honorable remembrance. Firm in his friendship to William Penn, and in his adherence to his personal religious opinions, a zealous and useful citizen, honorable and upright in every relation of life, he has also the still further credit of having been the first to tincture the rising colony with literature and all those amenities which learning brings in its train. * * * * * =USEFUL ARTS OF THE GREEKS AND ROMANS.= =BY CHARLES WILLIAMS.= In an age when the useful arts have attained so high a development, we are, perhaps, prone to treat with neglect, or even unmerited contempt, the efforts of the nations of antiquity in the same sphere. It is not here as in the province of thought and genius. The poet, sculptor, painter, or philosopher, at the very outset of his labors, is accustomed to contemplate and mould himself to those perfect models spared for his use by the hand of Time. But the artificer, whose nearer concern is with the material and its uses, not with the form, is apt to fix a less ample scope; and while intent on supplying a want, often forgets that the same necessity indicated a similar effort thousands of years ago--an effort often crowned with the same results. “The world grows old and again grows young,”
