 ther stream escaping from the primitive districts towards the 

 south, through a fissure called El Puerto Blanco, a few miles 

 in an easterly direction is soon after crossed ; between which 

 and a fourth stream passing by the villages of Jayena and 

 Fornes, there is an undulating marly tract partially under cul- 

 tivation, and rising into a low ridge, in part of its area crowned 

 by a few strata of conglomerate. All these streams last men- 

 tioned unite in one a fevv miles towards the north-west, and 

 form the rivulet crossed at Cacin, on the road from Gra- 

 nada to Alhama. Descending the slope from this little tract to 

 the stream last alluded to, a long slip of ground is perceived 

 to border its right bank, immediately beyond which the country 

 begins to rise, and subsequently takes an elevated table-land 

 form, stretching northwards towards Agron, a village on the 

 road from Arenas to Granada. Horizontal beds of gypsum are 

 observed along the first part of the ascent, and a low escarp- 

 ment, which I had not time to examine, but which probably is 

 formed of the compact paludina limestone, borders its summit. 

 Following this stream upwards to Jayena, several low escarp- 

 ments along its banks exhibit horizontal strata of a semi- 

 indurated whitish marly limestone, and the slip of land just no- 

 ticed opens out into a richly cultivated little valley, in the im- 

 mediate vicinity of this neat and chearful village. 



In the low ridge, composed of horizontal strata, of whitish 

 soft marly limestone, in places full of paludinae, which borders 

 this narrow valley towards the north, near and above Jayena, 

 there is a ravine close to the latter village, in whose banks a bed 

 of brown * coal has lately been discovered. 



The valley extends three or four miles above Jayena, pre- 

 senting in every little escarpment the same marly limestone. 

 Here I terminated my excursion, and traversing the primitive 

 chain which confines it towards the south, proceeded by a moun- 

 tain road over the magnificent pass called Las Vueltas -f-, or 



• The scarcity of fuel in the mining district along the Southern Mediter- 

 ranean coast of Spain, and the prohibition of English coal, has induced a 

 great commercial and mining house in Malaga, to make excavations here, in 

 order to employ it as a substitute.
