If the etymology of the name _Renelle_ is doubtful, the utility of the stream at least is not so. It supplies numerous tanneries, of which there are still a great many in the street which bears its name. This sort of industry is very ancient in Rouen, and has never been established in any other part of the town. On the 22nd of march 1560, the parliament issued an act, ordering all the tanners to remove their establishments to the _Eau-de-Robec_; but, they said that they required clear water to carry on their trade, and therefore, were allowed, by order of the king, to remain on the Renelle. This rivulet comes from the Gaalor spring, and flows from the fountain of the _Bailliage_, almost in a straight line to the Seine, into which it falls. FOUNTAINS. The more churches there were in a town, there should be as many public fountains. Under the ancient law, a tub was placed at the entrance of the temples, in which the priests washed their hands and feet; under the new, and in imitation, fountains were placed near the churches, where the christians, before entering, washed their face and hands. This remark was applicable especially, in Rouen, before the revolution, where the number of churches and fountains was quite equal. There are not now thirty seven parochial churches; but we can still count thirty six public fountains, not including those in many private houses. Of all these fountains, only seven merit particular attention, from their architectural and historical character. They are the fountains of the _Croix-de-Pierre_, the _Crosse_, the _Grosse-Horloge_, the _Vieux-Marché_, the _Pucelle_, _Saint-Maclou_, and _Lisieux_. FOUNTAIN OF THE CROIX-DE-PIERRE, _Carrefour Saint-Vivien._ There formerly existed, not far from the fountain known at present under the name of the _Croix-de-Pierre_ (stone cross), a cross, which had been raised through the piety of the inhabitants; but, we now can find no authentic document of the period of its being erected; all we know is that it had been rebuilt in the year 1628. This fountain is composed of three partitions in the form of a pyramid, and is ornamented with some statues; its appearance is exceedingly fine. One may still form an idea of the beauty of its architecture, in spite of its ruinous condition, and even the repairs it has undergone. FOUNTAIN OF THE CROSSE, _At the corner of the streets des Carmes, and de l'Hopital._ This is a small monument in the gothic style of the end of the XVth century. The sculptures which decorate it, are remarkable for their fineness and delicacy. It is surmounted by a royal crown. Its name comes from its being situated at the corner of the house, which had for sign the crozier belonging to the monks of Notre-Dame de l'Ile-Dieu. Some etymologists see in the word _Crosse_, an alteration of the english word _cross_. In the year 1815, this fountain was completely renewed. FOUNTAIN OF THE GROSSE-HORLOGE,
