rocks frequently occurs at the base of the hills, and often forms 
smaller rapids. 
After the junction of the Sarabia the hills become inconsi- 
derable, and almost entirely disappear a little below the river 
Jumuapa (or de la Puerta) ; the rapids also are less frequent 
and the last of them, called the Suchil, is seen just before 
reaching the mouth of the river Jal tepee (or de los Mijes). 
The rivers Sarabia, Jumuapa, and Jaltepec enter the Coat- 
zacoalcos on the left bank, and next to them the Chalchijapa 
on the right hand. The two first descend from the sierra of 
Santa Maria Guienagate, and although the Sarabia has much 
water it is not navigable, on account of its course being too 
precipitous, and having near its mouth a fall which impedes 
the entrance of canoes ; but the Jumuapa can be ascended by 
them, in the rainy season, to the point named the Paso del la 
Puerta; from whence the road to San Juan Guichicovi is 
shorter and better than the one from the Paso del Sarabia. 
The river of Miges has its source in the sierra of the same 
name in the district of Villa Alta; and notwithstanding the 
rapidity of its current, it is navigable all the year round for 
canoes to a spot called Tutla, distant 7| miles from the vil- 
lage of Trinadad. The distance from Tutla to the mouth, 
calculating by the time occupied in ascending it, may be rec- 
koned at 50 miles. The river Chalchijapa carries also much 
water; the Indians of Santa Maria ascend it for five days with 
rafts, and then cross by land to their village, which is 38 miles 
distant from the point where they leave their rafts. 
Between the confluence of the Chalchijapa and the point 
of Horqueta, where the river is divided into two branches, 
the stream Colorado, the rivers Naranjo and Penas Blancas, 
and the stream Cuapinoloya join the river by its left bank, 
and the brook Churriagao by the right ; the latter and the 
Penas Blancas come from large lagoons not far distant. 
The general course of the Coatzacoalcos from the conflu- 
ence of the Malatengo to that of the Jumuapa is from S. to N. ; 
then it runs N. W, until it meets the Jaltepec ; and thence to 
the bar its course is N. E. The length from the mouth of the 
Malatengo to the Sarabia is 22 miles ; from the Sarabia to
