which, at the water s falling down to its centre again, fell down with such a force 

 upon the land, that it was broke to pieces ; and a boat was found at the distance 

 of 2 musket-shots within land from the sea. 



At Salle, there happened very great damage, several houses having fallen 

 down. The waters came up with such rapidity, that they came into the city, 

 and at their falling down, great quantities of fish were found in the streets, and 

 many persons were drowned: 2 ferry-boats overset in the river, and all the people 

 on board were also drowned; and a great number of camels, that were just then 

 going for Morocco, were carried away by the waters. 



At Fez, vast numbers of houses fell down, and a great many people were 

 buried under the ruins. At the Scloges, a place where the Barbai-ians live, not 

 far from Fez, a mountain broke open, and a stream issued out as red as blood. 



At Mequinez, a vast number of houses fell down, and a great many people of 

 both sexes were buried under their ruins ; the convent of the Franciscan friars 

 fell down to the ground, but the friars were saved. 



At SafFe, several houses fell down, and the sea came up as far as the great 

 mosque, which is at a great distance from the sea. 



At Morocco, by the falling down of a great number of houses many people 

 lost their lives ; and about 8 leagues from this city, the earth opened, and swal- 

 lowed up a village, with all the inhabitants, (who were known by the name of 

 the sons of Busunba) to the number of about 8 or 10,000 persons, with their 

 cattle of all sorts, as camels, horses, horned cattle, &c. and soon after the earth 

 was closed again, in the same manner as it was before. 



At Fez and Mequinez, on the 18th of November there happened another 

 earthquake, which was more violent than the first, and lasted till break of day 

 the 19th; during which time great numbers of houses fell down at Fez; many 

 people of both sexes were buried under their ruins ; and as to Mequinez, there 

 are but few houses left standing. The people killed by the falling of the houses, 

 besides the wounded, are numberless ; and in the part of the town called the 

 Jews' Habitation, only 8 persons were saved. 



At Saijon Hills, one of the hills was rent in two ; one side of which fell on a 

 large town, where there was the famous sanctuary of their prophet, known by 

 the name of Mulay Teris ; and the other side of the said hill fell down on an- 

 other large town, and both towns and the inhabitants were all buried under it. 



The famous city of Tasso was wholly swallowed up ; no remains left. 



This last earthquake was likewise felt at Tetuan and Tangier, but without 

 any other damage than that the fountains of Tangier were dried up for 24 hours.
