Some of our readers will scarcely realise the enormous Importance of the-telescope the-telescope the-telescope and what Is done by means of it. . Bines the time when Oal- Oal- Ilea Invented the telescope It has passed passed through a form of evolution-that evolution-that evolution-that allies allies It to the history of civilisation. While astronomy, as we know, la, of sll sciences, the one mont removed from the ephere of commercial renults, yet the telesoope. In some form or another, Is the one and only means we have of ravlgatlng ships, of measuring wide expanses of territory, of determining' latitude and longitude, and of keeping tiros. The exaot time can be taken by observing a fixed star, and there ts no reason why the new observatory at Ottawa by means Of this great telescope telescope should not set and regulate, every every night, official clocks In Ottawa.

It Is' safe to predict that ' when the .government observatory at the Cen tral Experimental Farm Is ready It will be ft'plac of great attraction to sightseers and an object of great Interest Interest to the ctttsens and to every visitor, and In order that every person may Indulge Indulge the anticipation of looking at the stars through this great Instrument we may say on the autliorlty of the chief astronomer, Mr. W, F. King, that he will be happy Id showing the telesoope to visitors. WHAT IT IS FOR.
