ON THE BANKS OF THE RIO GRANDE.

The Rio Grande is not an imposing river at Laredo, and our young friends were disappointed when they saw it. They had looked for a stream of magnitude, as implied by the name, and were not prepared for one that could be forded without much danger, and was so diminutive as to remind them of those rivers of the Western States where it is necessary to use a sprinkling-pot at certain seasons of the year to let strangers know where the stream is. The Doctor told them that the Rio Grande was known as the Rio Bravo in the lower part of its course, and Frank suggested that it was because the river was very brave to come so far with such poor encouragement.

INDIAN WATER-CARRIERS.

"But the stream which now looks so insignificant," Doctor Bronson explained, "is subject to periodical floods, owing to the melting of the snows in the mountains where it takes its rise. They begin in April, reach their greatest height in May, and subside in June, and while they last they fill the whole bed of the stream, and overflow the banks wherever they are low. Some of its tributaries at such times are roaring floods, while ordinarily they are only dry beds, where not a drop of water can be seen for many miles. But if you dig a few feet into the sandy bed of these streams you will find water; emigrants travelling through this country carry an empty barrel from which both heads are removed, and by sinking this barrel into the sand they obtain a plentiful supply of water. A knowledge of this fact has saved many lives, and ignorance of it has caused deaths by thirst when suffering might easily have been avoided."

The first bridge erected by the railway company at Laredo was of wood; it served its purpose until the first flood, when it was torn from its foundations and carried away. The present bridge is a substantial one of iron, and promises to last a long time.

From Laredo the train moved slowly across the river, along a bridge whose height was intended to make it secure against the severest floods, until it reached the station of Nuevo Laredo, on the Mexican side, two or three miles from Texan Laredo. Here there was an examination of baggage by the Mexican customs officials; they were polite, and our friends had learned from long experience in custom-houses to be polite in return. The result was that the examination of their belongings was very slight, while that of some of the passengers who displayed ill manners was much more severe. The Doctor and the youths produced the keys of their trunks and opened them before being asked to do so, and promptly announced the contents of the receptacles. They had nothing dutiable, and in a very few minutes the ordeal was ended.

Frank made the following note about the Mexican custom-house:

"Mexico is a land of high tariffs, and pretty nearly everything that can be imported is taxed. Machinery was formerly imported free, but it is now subject to duty, and so is almost everything except agricultural and scientific instruments and books. There is also a duty on packages apart from their contents, and there is a heavy duty on all kinds of carriages. Baggage for personal use is admitted free of duty, unless there is reason to suspect that the owner has an intention to sell; two or three suits of clothing will pass without question, but ten or twelve would be liable to detention and duty. The laws require that the examination of baggage shall be conducted 'liberally, and with prudence and moderation,' and certainly we have no occasion to complain of discourtesy. In addition to clothing 'not excessive in quantity,' a traveller may have two watches with their chains, a cane, an umbrella, one or two pistols with equipments and cartridges, one hundred cigars, forty small packages of cigarettes, a rifle or fowling-piece, one pound of smoking tobacco or snuff, and any musical instruments in actual use except pianos and organs. When a resident of the United States crosses the Rio Grande into Mexican territory with his own carriage he must pay the duties on the vehicle, or give a bond for their payment in case he does not return to the United States.
