or HARROW-ON-THE- HILL , an English town in Middlesex. Its "visible church," which crowns the hill-top, was founded by Lanfranc, and rebuilt about the middle of the 14th century. HARROW SCHOOL was founded in 1571 by John Lyon, a wealthy yeoman, who died in 1592; but the original red brick school house (now the Fourth Form School) was not built till 1608- 1615. New buildings have been added since 1819, the chief of these being the Second-pointed chapel ( 1857), Vaughan Memorial Library (1863), and the om (1877). the semicircular Speech-room The school was primarily intended to afford a free education to 30 poor boys of the parish; but the statutes, drawn up by the founder two years before his death, provided also for the admission of "so many foreigners as the place can conveniently contain" and it is to that provision that Harrow, though not richly endowed, owes its proud position among the great schools of England. The age of admission is 12 to 14; and there are six or seven entrance scholar- Vol. IV-Cyc-EE ships, of from $150 to $400 per annum, offered every Easter.

or Drag, a well known agricultural implement. The first harrow was doubtless a tree top drawn by a person. Then came perhaps the crotch of a tree with long knots left to serve as teeth. The old A-harrow long used in England and in this country consisted of three pieces of timber framed in the shape of the letter A and provided at first with wooden, then with iron teeth, with which to scratch the ground. The drag of the northwest, used in grain raising countries, consists of from two to five wooden frames, each having the shape of a diamond. In level wheat regions four of these light frames are jointed to a central A-shaped section to make a drag. They are attached to a four-horse evener and have a sweep of from twenty to twenty-four feet. The number of teeth in the five sections is as high as 150. An active four-horse team will harrow from twenty to thirty acres a day with a drag of this sort. A writer in Bailey's Cyclopedia of Farming speaks of a steam traction drag with a sweep of 100 feet, capable of harrowing thirty acres an hour, or a section in two working days.
