 The overland mail route to California has been selected by the postmaster general, with the appreciation of the President, and the loca- ton of that route will meet with the liveliest satisfaction from every citizen of Arkansas. The route is as follows: Beginning at St. Louis and Memphis, on the Mississippi river, thence forming a junction at Little Rock, thence in the direction of Preston, to the Rio Grande, at the most suitable crossing of that river, near Fort Fillmore or Donna Anne, thence along the new road now being made under the di- rection of the Secretary of the Interior to Fort Yuma, thence by the best passes and through the best valleys for safe and expeditions stag ing to San Francisco. The contract has been given to a company who are members ot the largest express companies in the country, whose
 
 emergency. The amount paid for semi-weekly service is $595, ,OOO per annum.
 The contract will go into operation with as little delay as possible, and will add greatly to the rapidly increasing prospects of Arkansas. The selection of this route indicates with a considerable degree of certainty the location Of the route of the Pacific railroad, and the pros poets of the Cairo and Fulton railroad are thus enhanced. The next movement after the sue cessful operation of the overland mail will be the establishment of a telegraph line from the Mississippi to San Francisco.
 The late know nothing national convention held at Louisville, did not create much notice from its insignifcance as to numbers and tal- ents. But the material composing the conyen- ton, and the tendency of the whole concern to fuse with black republicanism against the democratic party, is fraught with danger to the Union. As sequence to the action of that convention, Speaker Banks has been nomnat- ed by the know nothings, as also the black re- pubIicans of Massachusetts, as their candidate for Governor No doubt'o his election, but the know nothing press at the south will be as oblvous of his antecedents, when they chronicle his success as they have been to in form their readers of his nomination by the party.
 This party is emphatically dead at the south, and what little of life remains in it is manifest ed n spasmodic efforts to recover breath, which however, only tend to show more garingly the huge doformity of its proportions. At the municipal election held here on the 1st of the past month, it gave one of its exhibitions, which entailed disgrace upon the national cap tal, and but for the prompt and efficient steps taken by the Mayor and President the city would have been given to rapine, murder aud coullagraton. During the present week the grand jury will make thorough investigation of the causes of the late riot, and take such action as the result of that investigation will call for. In the mean time some half dozen know nothings who took charge of the polls n one of the wards of the city, and would uot permit democrats to vote, have been tried by the criminal court, found guilty, fined, and sent to jail for one year.
 The reduction Of the tariff, which took place on the lst inst, will not diminish the revenue for the first quarter, as large amount of goods were landed in anticipation of that event. and will at once be taken ont. To June P, there was in the treasury, subject to draft $2O 159- OH II, and of this amount at the depository at Little Rock $2t6.99l s.
 Fears are entertained that we are on the eve of mighty revulsion in the commercial and monetary affairs of the country, owing to the wild and extrayasant spirit of speculation now abroad in the land, especially in wild lands. There is too much reason to believe that this mania has been carried too far, and we may have another such smash up as '36 and '37 On the other hand, it is believed that money Is so abundant, and the price of labor and the products of labor So Ligh 10 fears ncel be en- tertaned of serious revulsion That if it comes t will only effect those who have ope- rated without capital in the foncy way At ali events it is the part of wisdom, that in the present excited state lookout should be keIt lor the breakers ahead.
 1 had the pleasure few days since of meet ing with J. l.. Lollowell, esq, of Arkansas who was going east on business and pleasure, and who informed inc it was his intention to remove to Little Rock shortly after his return home. He $ the same inveterate bachelor as If yorc, but am sure if he prizes single bles. scdne8s, he had better not make the contem- plated change in his residence, for "they do say" the array of female beauty and worth at Little Rock cannot be rosi,tel Be that as it may, however, wish him success in his new home personally, and Gas Henry Wilson would say) "othertose"
