258 EARTHQUAKES. [Lesson XXXV, 



in many places very remarkable. At Colares, on 

 the afternoon of the 3 1 st of October, the water of a 

 fountain was greatly decreased : on the morning 

 of the first of November, it ran very muddy; and, 

 after the earthquake, returned to its usual state 

 both as to quantity and clearness. On the hills, 

 numbers of rocks were split : and there were 

 several rents in the ground, but none considerable. 

 In some places where formerly there had been no 

 water, springs burst forth, which continued to run. 

 Some of the largest mountains in Portugal were 

 impetuously shaken as it were from their founda- 

 tion; most of them opened at their summit, split 

 and rent in a wonderful manner, and huge masses 

 of them were thrown down into the subjacent 

 valleys. From the rock called Pedra de Alvidar, 

 near the hill Fojo, a kind of parapet was broken 

 off, which was thrown up from its foundation in 

 the sea. At Varge, on the river Macaas, at the 

 time of the earthquake, many springs of water 

 burst forth ; some spouted to the height of 18 

 or 20 feet, throwing up sand of various colours, 

 which remained on the ground. A mountainous 

 point, seven or eight leagues from St. Ube's, cleft 

 asunder, and threw off several vast masses of rock, 

 In Barbary, a large hill was rent in two : the two 

 halves fell different ways, and buried two large 

 towns. In another place, a mountain burst open, 

 and a stream issued from it as red as blood. At 

 Tangier, all the fountains were dried up, so that 

 there was no water to be had till night. A very 

 remarkable change was observed on the medicinal 



waters
