Oiipt. H. W. llowgate, in a recent letter, says bis polar eolonization solióme naturally divides itself undor throo heads, as follows: 1. The organization. oí a propei-ly equipped expedítioh, with ampie means, botli to maintain a colony and to prosecute efiforts to reach the North pole. To this end Congreesional aid is to be sought, and a bilí has been introduoed into the lower houe and properly referred. This provides that -$50,000 be appropriated, to be used under the direetion of the President, in org;:niziDg one or niore expeditions, with a yiew to establishihg a temporary colony somewhere north of the Sist parallel foi the purpose of exploration ; that suitable public vessels be selected and officors áetailed for the expedition, and that the National Academy of Sciences be invited to assist with its advice. ín case this bilí fails to pass, the necessary funds, it is hoped, could beraised by private subscriptien. 2. The Establishment and maintenance of the colony. Proper material for shelter, ready to be immediately put up, should be taken by the vessel carrying the colonista. With this pre caution tb ey could be made as cornf ortable as the signal service officials at present are at the summit ot Pike's peak or of Mount Washington, although the exposure of these last mentioned would be for a shorter period. Proper f ood should be provided in proper quantities and sufficient variety. Fresh meat in proper quantities can be bad in the immediate vicinity of the propesed colony. With proper food and shelter ihere is no trouble about keeping men even at such latitudes in robust health. 3 Explorations toward the pole. - The officer in charge being on the spot would be ablo to take advantage of all favorable opportunities, and, no doubt, in three years' time or leas, would discover the pole itself, if such a feat is witliin the reach of human effoita. Tho vessel taking the colonista should return immediately, and flae colony be provided with sledges and small boats for their penetrations northward. ' Gapt. Tyson, of the Polaris party, enthusiastically mdoracs Capt. Howgate'a scheme. Ho characterizes it as the most practicable yet devised, and thinks the scientific socicties of the country ought to memorialize Oongress in favor of the bilí before mentioned. If the United States, he says, provea too niggardly to prosecuto this enterprise, Eugland or Germany will undoubtedly move in the matter and secure the honor of acoomplishing the desired resu't.
