There were few reptiles; the only dangerous kinds were the rattlesnake, and one striped with black, yellow, and white, about four feet long.  Among the lizard kind was one about nine or ten inches in length, exclusive of the tall, and three inches in circumference.  The tail was round, and of the same length as the body.  The head was triangular, covered with small square scales.  The upper part of the body was likewise covered with small scales, green, yellow, black, and blue.  Each foot had five toes, furnished with strong nails, probably to aid it in burrowing, as it usually lived under ground on the plains.

A remarkable fact, characteristic of the country west of the Rocky Mountains, is the mildness and equability of the climate.  The great mountain barrier seems to divide the continent into different climates, even in the same degrees of latitude.  The rigorous winters and sultry summers, and all the capricious inequalities of temperature prevalent on the Atlantic side of the mountains, are but little felt on their western declivities.  The countries between them and the Pacific are blessed with milder and steadier temperature, resembling the climates of parallel latitudes in Europe.  In the plains and valleys but little snow falls throughout the winter, and usually melts while falling.  It rarely lies on the ground more than two days at a time, except on the summits of the mountains.  The winters are rainy rather than cold.  The rains for five months, from the middle of October to the middle of March, are almost incessant, and often accompanied by tremendous thunder and lightning.  The winds prevalent at this season are from the south and southeast, which usually bring rain.  Those from the north to the southwest are the harbingers of fair weather and a clear sky.  The residue of the year, from the middle of March to the middle of October, an interval of seven months, is serene and delightful.  There is scarcely any rain throughout this time, yet the face of the country is kept fresh and verdant by nightly dews, and occasionally by humid fogs in the mornings.  These are not considered prejudicial to health, since both the natives and the whites sleep in the open air with perfect impunity.  While this equable and bland temperature prevails throughout the lower country, the peaks and ridges of the vast mountains by which it is dominated, are covered with perpetual snow.  This renders them discernible at a great distance, shining at times like bright summer clouds, at other times assuming the most aerial tints, and always forming brilliant and striking features in the vast landscape.  The mild temperature prevalent throughout the country is attributed by some to the succession of winds from the Pacific Ocean, extending from latitude twenty degrees to at least fifty degrees north.  These temper the heat of summer, so that in the shade no one is incommoded by perspiration; they also soften the rigors of winter, and produce such a moderation in the climate, that the inhabitants can wear the same dress throughout the year.
