What is most commonly recognized in Colombia as guaco, or Vejuco del guaco, would appear to be Mikania Guaco (Humboldt and Bonpland, Pl.
The odour alone of guaco has been said to cause in snakes a state of stupor and torpidity; and Humboldt, who observed that the near approach of a rod steeped in guaco-juice was obnoxious to the venomous Coluber corallinus, was of opinion that inoculation with it imparts to the perspiration an odour which makes reptiles unwilling to bite.
1 They are particularly important in that they counteracted the popular and interestingly written books of Max Muller: for instance, Muller, like Renan and Wilhelm von Humboldt, regarded language as an innate faculty and Whitney considered it the product of experience and outward circumstance.
Humboldt, for example, defined his view of the scope of plant geography as follows:
Alexander von Humboldt (1769-1859) was the first modern geographer to become a great traveller, and thus to acquire an extensive.
The theory of geograph y was advanced by Humboldt mainly by his insistence on the great principle of the unity of nature.
The mountains also increase in height and importance as far as the East Humboldt range, a lofty mass about 60 m.
On its eastern slope the waters soon disappear within the bed of narrow canyons, but break out again at the foot in icecold springs that form the source of the Ruby and Franklin lakes; on its western side the descent is more gentle, and the waters form the South Fork of the Humboldt river.
Toward the Humboldt, but seldom has sufficient volume to enable it to reach that stream.
Of the California boundary lies a third important range, the Humboldt Mountains, whose highest point (Star Peak) is 9925 ft.
From the valley of the Humboldt river southward the plateau gradually rises until the divide between this stream and the Colorado river, in the vicinity of the White Pine Mountains, is reached.
Of the basin streams the Humboldt is the most important.
This stream empties into the Humboldt lake, the overflow from which goes into the so-called Carson Sink.
Several varieties of poplar are found in the upper canyons, and trees of the willow-leaved species in the Humboldt Mountains often attain a height of 60 ft.
In the central, north-eastern and north-western sections, embracing the counties of Nye, Elko and Humboldt, the average annual rainfall varies from 7 to 8 in.; in the west-central section, at the foot of the Sierra, the average is about 10 in.
At the head of the Humboldt river frosts are of almost nightly occurrence, and in the Carson Valley damaging frosts often occur in June.
The three principal areas in which irrigation is practicable are along the Humboldt river, in the plains watered by the Carson, Truckee and Walker rivers, and at the foot of the mountains along the western edge of the state.
The most productive part of the state is the Humboldt Valley and the region near Pyramid Lake, including the counties of Humboldt, Elko and VVashoe.
These first appeared in large numbers in the lower part of the Humboldt Valley in the summer of 1906, and in October and November 1907 it was estimated that they numbered on certain ranches from 8000 to 12,000 on every acre.
After unsuccessful attempts to rid themselves of the mice, the farmers appealed to the United States Biological Survey, and alfalfa hay poisoned with strychnia sulphate was used successfully in the Humboldt Valley in January 1908 and in the Carson Valley, where a similar plague threatened, in April 1908.5 Minerals.
A little graphite is produced in Humboldt county.
Considerable quantities of the following minerals have been found: barytes (heavy spar), magnetite (magnetic iron ore), and pyrolusite (manganese dioxide) in Humboldt county; roofing slate in Esmeralda county; cinnabar (ore containing quicksilver) in Washoe county; haematite in Elko and Churchill counties; cerussite and galena (lead ores) in Eureka county; and wolframite (a source of tungsten) at Round Mountain, White Pine county.
The oldest of these trunk lines, the Southern Pacific (formerly the Central Pacific), follows the course of the Humboldt and Truckee rivers.
Half a century later a party of trappers of the Hudson's Bay Company entered Nevada and plied their trade along the Humboldt river.
In 1806 he journeyed to Italy, and was for more than a year private tutor at Rome in the family of Wilhelm von Humboldt, who became his friend and correspondent.
As early as 1804, Humboldt expressed the opinion that petroleum was produced by distillation from deep-seated strata, and Karl Reichenbach in 1834, suggested that it was derived from the action of heat on the turpentine of pine-trees, whilst Brunet, in 1838, adumbrated a similar theory of origin on the ground of certain laboratory experiments.
This is due as much to the inspiriting teachings of Ritter and Humboldt as to the general culture and scientific training combined with technical skill commanded by the men who more especially devote themselves to this branch of geography, which elsewhere is too frequently allowed to fall into the hands of mere mechanics.

In 1859, however, he entered the city disguised as a carter, and, through the influence of Humboldt with the king, got permission to stay there.
Von Humboldt (1769-1859).
Humboldt found it among the native tribes of the Orinoco valley, where it is called pirijao.
But on the east of the Anambaruin-ula it once more contracts to two main ranges, the more southerly being that which Przhevalsky called the Humboldt Range (crossed by a pass at 13,200 ft.).
The next range is Humboldt or Ama-surgu range, which runs N.W.
Von Humboldt to refer to him as "Botanicorum facile princeps."

It is denominated by Humboldt 5 the " zodiac of hunters and shepherds," and he adds that the presence in it of a tiger gives it an exclusively Asiatic character.
Thus a nakshatra-mad 3 Humboldt, Vues des Cordilleres, p. 168.
The correspondence does not, however, extend to the stars; and some coincidences adverted to by Humboldt between the nakshatras and the zodiacal animals of Central Asia are of the same nominal character.

Von Humboldt especially drew attention to Varen's genius and services to science.
Other parks are Lake Park, also on the lake shore, at North Point, where stands the waterworks pumping station with its tall tower; Riverside and Kilbourn Parks, east and west respectively of the upper Milwaukee river, in the northern part of the city, Washington Park on the west side, containing a menagerie and a herd of deer; Sherman Park on the west side, and Kosciusko, Humboldt and Mitchell Parks on the south side.
