MORMON EMIGRATION.—Since the naviga-tion of the Ohio river opened this spring, 1500 Mormon emigrants passed through Pittsburg, on their way to Utah, and others are daily expected. They are understood to be from Great Britain, where Mormon proselyt-ism makes steady progress. At Liverpool there is a Mormon agency, supported espe-cially for the purpose of aiding emigration. It has this year sent off upwards of 3600 emi-grants. Of these, the expenses of 1100 were paid. We see it stated, says the North American, that many of these emigrants were converted in Liverpool, where, it is supposed, the Mormon preacher circulates among the poorer classes of emigrants seeking passage to America. However this may be, appearances indicate that the accessions to the Mormons this year will be greater than for any previous one. In view of the recent news from the Salt Lake, respecting the complicity of the Mormon chiefs in the murder of Captain Gunnison and his party, the increase in the number of emigrants cannot but be regarded with disquietude, as it is evident that we shall have very serious trouble yet with these people.
