The greatest length of the province of Buenos Ayres is 66 

 maritime leagues, extending from El Arroyo del Medio, situated 

 at the north-west extremity, in from 33° to 33.30° S. Lat. 

 as far as La Eusenada de Samborombon, at the mouth of the 

 Rio del Salado, in 36° S. Lat. forming the south-eastern extre- 

 mity. Its diameter is 23 leagues, giving to the whole province 

 a superficies of 1513 square leagues. 



The river Salado formed the southern boundary of the pro- 

 vince of Buenos Ayres, while under the dominion of Spain ; but 

 since obtaining their independence, numerous estancias, or 

 estates for breeding cattle, have been formed, and various mili- 

 tary stations have been established a considerable distance to the 

 south for their protection. These estancias are most numerous 

 on that side which borders on the Atlantic, and being situated 

 in the finest and most fertile part of the country, are rapidly 

 increasing in number, and will speedily become continuous, as 

 far south as Baya Blanca, in 39° S. Lat. where about three years 

 ago, a new city was founded, named New Buenos Ayres.
