This Territory is bounded on the North by the Province of Mendoza, on the West by Chile, on the South by the Territory of the Rio Negro, and on the East by the Territory of the Pampa Central. Neuquen, though Argentina at large knows little of it, grows more wheat than any other National Territory, except the Pampa Central, and more alfalfa than any except the last named and the Territory of the Rio Negro. It also sends small quantities of potatoes and other table vegetables to Chile. Its chief exports to that country consist of cattle and sheep on the hoof. The whole of the Andine side of Neuquen is extremely picturesque, and abounds in fertile valleys well watered by mountain streams. These streams, after their arrival at the foot of the Andine range, form a network of ultimate tributaries of the great rivers Colorado and Negro; after having formed a whole system of lakes of which Nahuel Huapí is the largest. The scenery of this lake, with the great snow-covered volcanic mountain TRONADOR (the Thunderer) on its Southern end, is Scandinavian in its tree-clad magnificence. The superficial area of this lake is some 1000 square miles and its depth in some parts is over 700 feet. On one of its islands, Victoria, the enormously wealthy Argentine family of Anchorena have founded a colony to work its wealth of virgin timber, on a 99 years’ lease from the National Government. A number of small steam and sailing boats ply on this lake, gathering the wood, hides and other produce of the farms on its borders and bringing to the farmers their necessary supplies. Neuquen is credited with alluvial goldfields and has some copper. Its mineral wealth is as yet, however, really unascertained; the prospecting and tentative exploitation of it having been up to the present only done by syndicates or small companies whose resources have been too limited for the tasks they have set themselves in, from the point of view of transport, such inaccessible regions. The Western and South-Western parts of this Territory are rich in timber, and its Eastern plains should, with irrigation, repeat the prosperous history of the Pampa Central. It has many hot and other mineral springs, the medicinal and other virtues of which are already known in Chile; from which country they attract many sufferers from rheumatism and stomachic and other ailments. In dealing with all the yet little known outlying parts of the vast Argentine Republic one is apt to become wearisomely tautological in one’s endeavours to give some true idea of their enormous latent natural wealth. Yet if one set out, ever so modestly, to bring some conception of them home to the Northern Hemisphere, one must tell the truth even at the risk of reiteration. And the truth is that for the future wealth of all these regions there is only one word, INCALCULABLE.
