Into the Fleet, down the still well-marked valley by Farringdon Road, ran a stream sometimes called the Fleet River; it is plotted on some of the earlier maps, and its course has been traced in detail by Mr. Waller.[35] In an agreement as to the land of the nunnery at Clerkenwell, made at the end of the twelfth century, this stream is unmistakably called the Hole-burn; its valley ran north and south by Clerkenwell, and the river and gardens of the Hospitallers of Jerusalem are said to have been upon it.[36] It gave its name to Holborn Bridge and to some extra-mural cottages near by, on the road which passed over it. The modern name should mean Hole-burn-Bridge Street, just as Fleet Street meant Fleet-Bridge Street. Holeburn Street is found in 1249.[37] Cottages at "Holeburne," which had existed in the time of the Confessor, are mentioned in Domesday, and we may conclude that the Holeburn and Fleet had these names not only in King Edward's day, but in Alfred's. The upper part of the stream was also called Turnmill brook; it was the mill stream of London. Stow also gives the name of the River of Wells to this western stream just described, saying: "That it was of old called of the Wells may be proved thus: William the Conqueror in his charter to the College of St. Martin le Grand hath these words, 'I do give and grant ... all the land and the Moor without Cripplegate, on either side of the postern, that is to say, from the north corner of the wall as the river of the Wells, there near running, departeth the same moor from the wall, unto the running water which entereth the city.'"[38] He goes on to say that the stream (Hole-burn) was still called Wells in the time of Edward I., citing the Parliament and Patent Rolls of 1307; but on referring to the calendars of these documents I find that this name of Wells appears in neither. The first speaks of "the water-course of Fleet running under the bridge of Holburn," and the second of them calls it "the Fleet River from Holburn Bridge to the Thames." Moreover, the Hole-burn was far away from the north corner of the city wall by Cripplegate, and the land granted cannot have extended all the way to the present Farringdon Road (the bed of the old stream) and have included Smithfield. The land of "Crepelesgate," taken by William Rufus and restored to St. Martin's by Henry I., is probably the same, and to-day it may be represented by the parish of St. Giles. Surely the whole construction of the passage requires that the north-west angle of the walls should be the western limit of the land granted.
