There are some large estancias in the partido, the principal being:

The partido is bounded on the N. by Carmen de Areco and Chacabuco, on the W. and S. by the Rio Salado, which separates it from Bragado and 25 de Mayo, and on the E. by Navarro and Mercedes. The largest estancia is that of Don Juan N. Terrero, near Las Toscas, on the banks of the Salado: the Cañada de Peludos is the boundary between this estancia and Mr. Dowling's, which latter is in the partido of Chacabuco, The Cranwell estancia is S. of Terrero's, extending from the chacras of Chivilcoy down to the Salado: it is divided into nine portions, for Mrs. Cranwell and her eight children. The great establishment of Mr. James White and Señor Villarino is one of the finest in the west, and well worthy of a visit it extends in a line of four leagues from the town of Chivilcoy to the edge of the Salado, and is devoted partly to agriculture and partly to grazing. This was one of the first model farms in the country, when tillage was first experimented here, and Mr. White's enterprise and improvements contributed in no small degree to stimulate and promote agricultural industry in Chivilcoy. The country on all sides of Mr. White's place, for miles around, is a succession of rich grain-farms; and a couple of leagues further east is the estancia Sau Roman, the property of Don Manuel Lopez, and crossing the Cañada Rica we come to the estancia of Mr. Michael Ronayne. The lands of Biaus, Montenegro, and Ramos are washed by the Rio Salado; those of Pereyra Souza, Barrios, Rojas and Barrancos are close to the Arroyo Saladas, which separates them from Navarro and Mercedes. The greater part of the Gorostiaga estancia is in the partido of Chivilcoy, besides three square leagues in Mercedes, adjoining it comprises four establishments, San José, San Bernardo, San Patricio, and Santa Trinidad, each of which has a lagoon of the same name

and estancia house and plantation, and a large stock of sheep and cattle: there is a railway station on the land, called after the proprietor, and situate about midway from Freyre to Chivilcoy. The lands about Chivilcoy are very low, and watered by the Arroyos San Antonio, Hinojo, and Cañada de Chivilcoy, which fall into the Rio Salado. The Lobo estancia is a couple of leagues S.W. of Chivilcoy, and those of Torres and Ovejero are further westward. The prolonged line of railway to Bragado will traverse the chacras intervening between the estates of White and Cranwell, and across the Rio Salado in front of the large estancia of Don Mariano Biaus, in the partido of Bragado: this extension will be 25 miles long.

The returns of stock for Chivilcoy are-111,852 cows, 38,462 horses, 825 fine sheep, 875,624 mestiza sheep, 5,200 creole, and 4,300 pigs; being an average of 2,500 cows, 800 horses, and 20,000 sheep per square league. The land is variously valued from $200,000 to $500,000 per league. The Irish population is comparatively small, not exceeding 200 in number: they are visited by Father Lynch from Mercedes. The official returns of population are-10,690 Argentines, 347 Italians, 252 Spaniards, 220 French, 84 English, 21 Germans, 5 Indians, 43 various: total, 11,664. There are 298 houses, and 2,784 ranchos, including 266 pulperias: 16 alcaldes, 52 tenientes, 15 policemen, and 2,116 National Guards.

Chivilcoy promises to be the finest town in the camp. The streets are wide, the houses well-built; the plaza covers eight acres, and the aspect of the place is busy and prosperous. The basis of its vitality consists in the chacras, which form a zone of rich fertility on all sides, and the shops are well supplied with merchandise of every description. There is a first-rate club, with reading-room 50 feet long, billiard-tables, coffee-room, &c., the exterior being decorated with marble pillars. A public library has been recently started by Mr. Krause, to which President Sarmiento and General Mitre handsomely contributed. There is also a small theatre; and a printing-office is about to be established. The state-school is exceedingly handsome; over the front is a handsome statue of Our Lord bidding little ones to come unto him; this is the work of M. Duteil: the arrangements of the school are elegant and commodious, the attendance numbering 101 boys and 50 girls. A couple of years ago a new church was commenced, on a scale of unnecessary magnitude; the works have been of course abandoned, after a foolish outlay of money, and a very strange spectacle is now presented by the posts formerly used for scaffolding, which have taken root and blossomed luxuriantly. The best shops are in the plaza, and that of Torroba Brothers is a rendezvous for English neighbors. The town has a doctor, apothecary, photographer, auctioneer, and 85 shops,

The cacique Cóliqueo and some of his friendly Indians sometimes visit the town to buy necessaries. There are 237 rateable houses, of which the best are those belonging to

There is a large proportion of two-story houses, giving the town quite a European look. Castagnino's quinta is exceedingly pretty, and those of Krause and Bunge are famous for delicious peaches. The railway station is at some distance from the town, but there are always hack-coaches in waiting for the trains. The journey to Buenos Ayres takes 5 hours, and there are two trains daily, each way. Justice of Peace, Don Federico E. Gonsalez; Curate, Rev.

Chivilcoy is 4 leagues N.N.E. of the Rio Salado, 10 S.E. of Chacabuco, 11 S.S.W. of Carmen de Areco, 13 S.W. of Giles, and 11 W.S.W. of Mercedes.

SITUATE 11 leagues S.W. of Buenos Ayres, has an area of 41 square leagues, and comprises 162 estancias. It is bounded on the N. by the Matanzas river, which separates it from the partido of the same name, on the W. by Lobos and Navarro, on the S. by Guardia del Monte, and on the E. San Vicente. It is watered by the Arroyo Cañuelas, Cañada de los Pozos, and other tributaries of Matanzas river, but has no lagoons of any size. The partido has long been famous for its Cabañas of prize rams and ewes for improving the breed of sheep, and some of its establishments are remarkably fine. The camps are well-suited for sheepfarming, as they retain water to a late period in summer, and in making wells water is found at a very short depth. Agriculture is also attended to, there being no fewer than 308 chacras, covering about 15,000 acres of tillage. This partido was one of the first settled by Englishmen, and our countrymen number over 200. The land is valued at $400,000 per league. Total valuation 25,000,000, against 15,000,000 in 1862. Contribucion tax, $100,000.

The estancias of Whyte and McClymont are among the finest in the country: the first is called La Campana, situate between the Arroyo de Cañuelas and the Matanzas river, and is famed for its superior breeds of sheep, horses, and cows, mostly imported from England. This estancia is got up in thorough English style, at great expense, and was one of the first in Buenos Ayres to be completely fenced in. The M'Clymont estate runs S.E. from the town of Cañuelas, about two leagues, and is similar in character to the last these model establishments were founded by two enterprising Scotchmen, who may be regarded as having been the pioneers of industry in this part of the country: the mansion houses, farm-sheds, &c., are of the most comfortable kind, and surrounded by orchards, wheatfields, and extensive meadow lands. Halbach's estancia of Los Remedios, between Monte Grande and the Matanzas river, was another costly and valuable property, but it changed hands a couple of years ago; the buildings and plantations, were sold for a tithe of their value. No less unfortunate was a joint-stock co. called Sociedad Pastoral, chiefly devoted to the rearing and importing of fine sheep and cattle: the lands were
