pendium in vogue when it appeared, combining, as it did, practice and theory in luminous order. It forms a course of mathematics for the nautical men, containing as much algebra and geometry as is necessary for the demonstrations of the various problems which it comprehends. It is a text-book in the Royal Navy. Mr. Riddle was noted for the surprising quickness and accuracy with which he took celestial observations. Shortly after his retirement in 1851, his bust in marble was presented to him by his old pupils, officers in the Royal Navy, accompanied with the expression of their high esteem for his worth as a public and private man. The presentation was in the boys' department of Greenwich School, the Admiral (Sir C. Adams) and all the officers attending in full uniform. These were deserving honors for a long, useful, and honorable life. He retired on full salary. Succeeded by his son. He died in 1856, aged 68 years. FOURTH GENERATION. Jane Riddle (1), eldest daughter of Edward3 (3), was married in 1844, to Captain Petley, Royal Navy. Has issue. Prof. John Riddle1 (2), eldest son of Edward3 (3), was born at Newcastle-on-Tyne, England, in November, 1816; married Georgiana MacKenzie, daughter of Eneas MacKenzie of Newcastle-on-Tyne, the Northumberland historian, and had issue seven children, of whom hereafter. At the early age of fifteen Mr. Riddle was appointed an assistant master in the Greenwich Hospital Schools, and on the retirement of his father in 1851, was chosen to succeed him as head master. In 1846, he was elected a Fellow of the Royal Astronomical Society, and from that time till his death, was a regular attendant at its meetings, and an occasional contributor to its papers. He was appointed in 1854 Examiner in Navigation to the Science and Art department of the Committee of Council on Education, and held for many years a similar appointment in the Society of Arts. By both these Institutions his services were highly valued. As a teacher Mr. John Riddle was perhaps unrivalled, and his success in instilling into the minds of mere boys not only the practice, but the theory of navigation was very remarkable. The influence he possessed with his pupils was unbounded; and the good which he has accomplished, by stamping on a vast number of the scientific officers of the Royal Navy the impress of his own vigorous mind, was so great that his untimely death, which occurred Oct. 11, 1862, was looked upon as no other than a national loss. Mr. Riddle was not only a good mathematician and a successful teacher, but also an accomplished gentleman, with a great taste for poetry and the arts. In society he was a universal favorite; and his urbane manner and intellectual conversation will long be remembered by a large circle of sorrowing friends. His death was the result of a fall from a platform in his class room, which produced concussion of the brain, from which, after lingering sixteen days, he expired. The following is on a monument to his memory. To the memory of John Riddle, Esq., F. R. A. S., who died 11th of Oct., 1862, This tablet is erected by his colleagues, The Masters of the Royal Hospital Schools, their high appreciation of his uprightness and purity of his character, as exhibited in all the relations of life.

[UNITED STATES BRANCH.] James Riddell' (1), parents unknown, was born somewhere in the Lowlands of Scotland; became a commissioned officer in the army of William III, and being an uncompromising Presbyterian, fought from principle during the wars with the Catholic-Irish. He was probably at the battle of Boyne-water,* and possibly connected with the siege of Londonderry. He was rewarded for his services in the army by a grant * Boyne-water, or river, in the east of Ireland, rises in the Bog of Allan, and flows through Kildare, Kings County, Meath, and Louth. The Battle of Boyne took place on the banks of Boyne-water, near Oldridge, on the 1st of July, 1690, in which William III defeated James II. An obelisk, 150 feet high, marks the scene of the battle. of three townlands in the County of Armagh, in the North of Ireland, and subsequently went there to dwell. He is said to have married Janet Maxwell, a woman of Scottish descent, and by her had issue, a family of sons and daughters. SECOND GENERATION. James Riddell2 (2), a son of James' (1), was born in the County of Armagh, Ireland, about 1670-80; married Mary Henderson, of Scotch parentage, and continued this branch family, being his father's heir. He was a man of wealth and position, and of powerful physical strength. He lived to an advanced age, and died leaving three children, of whom hereafter. THIRD GENERATION. James Riddell (3), a son of James2 (2), was born in the city of Belfast (the author thinks a few miles out of the city proper), Ireland, in 1746; married Elizabeth Cowden, and had issue three sons, of whom hereafter. FOURTH GENERATION. Leander Riddle* (1), son of James (3), was born in Belfast, County Antrim, Ireland, in 1766; married Mary Brooks, and had issue several children, of whom hereafter. He was in the British naval service for four years; subsequently a cotton manufacturer. Emigrated to the United States, and settled in Pennsylvania in 1827, where he died in September, 1851, aged 85 years. James Riddle1 (4), a son of James (3), was born at (or near) Belfast, Ireland, and became ancestor of the Riddells of Belfast, which see. He was a half-brother of Leander. Alexander Riddle (1), a son of James (3), was born near Belfast, Ireland, and never married. He is said to have been a man of herculean strength, and feats accomplished by him were remarkable. FIFTH GENERATION. Elizabeth Riddle (1), eldest daughter of Leander1 (1), was born at Parkmount, near Belfast, Ireland, in 1798, and is now living at Glen-Riddle, Peun. Samuel Riddle" (1), eldest son of Leander (1), was born at Parkmount, near Belfast, Ireland, in 1800. He married for his first wife, Martha Mercer, and secondly, Lydia C. Doyle, of Chester, Penn., by whom he has issue four children, of whom hereafter. Mr. Riddle acquired a fair English education at a private academy, quitting it at an early age to enter a cotton-factory in Belfast. While at the latter place he acquired a practical knowledge of cotton-manufacturing, being thus occupied nine years. He then determined to seek a more profitable field, and in May, 1823, sailed for the United States, but was shipwrecked at Sable Island. He eventually reached Philadelphia, in the following August, his whole capital being now reduced to five Spanish dollars. He carried his seachest on his back to his boarding-house, and immediately obtained employment in a cotton-mill at Manayunk. He removed to Pleasant Mills, N. J., where he was employed about three years. During this time, by carefulness and thrift, he had accumulated a small amount of means, with which he commenced business on his own account. He rented a mill at Springdale, Delaware County, Penn., in 1827, and engaged in spinning cotton yarns with four hundred and eighty mule spindles, employing only ten hands. In three years' time he removed to a larger building on Chester Creek, and commenced operations with three hundred mule spindles, and the necessary machinery used in preparation; he remained there prosperously engaged for twelve years. In 1842 he purchased property at Pennsgrove, in Delaware County, which he named "Glen-Riddle," for Glen-Riddell, the residence of a branch of the family in Scotland. This locality was well chosen; a beautiful valley on Chester Creek, about fifteen miles from Philadelphia, was the place suited to Mr. Riddle's mind, and here he has added acre to acre and mill to mill, until at present the estate consists of a tract of land of several hundred acres, worth about three hundred dollars per acre. There are five large mills and more than two hundred dwellings in the town, occupied principally by the mill-operatives, of whom there are about five hundred employed. The town, a post-office, and railway-station derive their name from their projector, Mr. Riddle. The mills operate nearly ten thousand four hundred cotton and woolen spindles, with all the machinery for the preparatory work, and two hundred and seventy power looms; these are driven by two water-wheels and a powerful Corliss engine. Here Mr. Riddle has prosecuted his business for more than thirty years, with constantly increasing prosperity, as the demand for his manufactures augments every year. Mr. Riddle's personal appearance is very marked; he is short, quite corpulent, and carries an expression of great determination in his face. In conversation he is very jocose and sarcastic; has a great fund of anecdotes, and can relate them in a peculiarly interesting way. He is fully engaged in his business operations, conducting the various branches with great system and carefulness. He has admitted other members of the family, and the business is now carried on under the firm-name of Samuel Riddle, Son & Co. In addition to the business carried on at Glen-Riddle, they have a large business as commission merchants in Philadelphia. [The author was the guest of Samuel Riddle for a few days after the family meeting held in Philadelphia, in 1876, and will ever remember with the most pleasing emotions the hours passed in this beautiful village; every attention was bestowed by this hospitable family which could conduce to the enjoyment of my visit. On the 4th of July, Mr. Riddle's son, in company with the mother and little Maude, the youngest daughter, took me on a pleasant drive with a fine barouche drawn by a pair of noble horses; the route lay through a very rich farming district, and the prospect from some of the grand hills over which we made our way was extensive and picturesque; and the cherries that were gathered from the large trees by the roadside were delicious to the taste. Glen-Riddle was appropriately named. Beautiful hills surround the village on every side, and nestling at their base, embowered in groves of luxuriant hard-wood trees that grow along the margin of the creek, stand the mills, and neat, white dwellings, where home the families employed by Mr. Riddle. Directly in front of the mansion-house of Mr. Riddle rises a large hill, the surface in smooth pastures, except near the summit, where we reach the borders of a beautiful grove of wide-spreading trees, a cool and delightful restingplace in a summer day. The family residence is surrounded with parks and gardens, tastefully laid out and ornamented with a variety of plants and flowers; there are fountains pouring forth their sparkling waters upon the grassy banks along the garden avenues, and all overshadowed with the foliage of the wide-spreading trees that everywhere abound. The house, constructed of solid stone, is spacious and stately, situated on |
