54 
leagues distant from the village of Jaltipan ; and in this same 
branch of Mistan is the pass of Blancos, at a distance of 1 S 
miles from the large town of Acayucam, the capital of the 
district. 
The branch Apotzongo is 25 miles long, and on its right 
bank, 18 miles from Horqueta, is the village of San Miguel 
de los Almagres (or Hidalgo-titlan), the first inhabited place 
met with, proceeding down the river. Below this point the 
water in this branch is constantly 20 to 23 feet deep ; but a 
little above los Almagres between the strands of Mistan-grande 
and Gaviota, it is impeded by a considerable shoal. 
After the junction of the two branches, the Coatzacoalcos 
receives on its right the rivulet Ishuatepec, the stream of Otapa, 
and the river Coahuapa, the mouth of which is 10 miles from 
the lower end of the island of Tacamichapa. The source of 
this river is unknown, and the district it traverses is a desert ; 
it has been ascended in canoes for twelve days, which is the 
same time as that employed in going up from the bar of the 
Coatzacoalcos to the pass of Sarabia ; schooners have also 
sailed up it to a sugar plantation 7| miles above the entrance. 
At a spot three leagues higher up, it receives the river Coa- 
chapa, which, as already mentioned, collects the waters that 
leave the Coatzacoalcos at the turn of Cascajal. The stream 
Otapa comes from some small lagoons producing salt in abun- 
dance. 
Four miles and a half below the confluence of the Coachapa, 
but on the opposite shore, is the village of La Fabrica of 
Mina-titlan ; and at 4^ more below this, the river Uspanapan 
joins the Coatzacoalcos by its right bank. 
Half way between the river Coachapa and Mina-titlan is 
situated on the left bank in front of an islet, the common en- 
trance to the creeks Tacojalpa, Ojozapa, and Cuamecatan, in 
which the pine logs destined for the arsenal at the Havannah 
were formerly deposited. 
Of all the villages named by Don Tadeo Ortiz, only Mina- 
titlan and Hidalgo-titlan now remain, although their situations 
are indicated on the map. 
The Uspanapan is the most considerable of all the numerous
