Frederick CAMPBELL of the Crown Land Offuce, son of Nelson CAMPBELL, left yesterday morn. for Algoma Mills, accompanied by Harry JOHNSTON, C.E. in charge of the C.P.R. works in that neighborhood. Mr. Campbell will find in the boundless west a finer field for his genius and under the direction of his cousin, Allan RAMSEY, C.E., who occupies an important position on the C.P.R., will no doubt make his mark in his own chosen profession.
