460 CANADIAN LONGITUDEg, 



Fredericfcon and Quebec, the position of the Quebec Observatory 

 would have been quite certain, as the longitude of the former had 

 been obtained by frequent signals on many nights with Cambridge, 

 which by interchange of several hundred chronometers with Grreen- 

 wich, is supposed to have its meridional difference of longitude ascer- 

 tained with all the accuracy possible short of that to be arrived at by 

 the transatlantic cable. 



We were unable to again get telegraphic communication with Fre- 

 dericton on account of the submerged cable at Cape Rouge being 

 broken; but Professor "W. C. Bond, of Cambridge Observatory, 

 offered in the kindest manner possible to send and receive signals to 

 and from Quebec ; on the 21st September and 9th October, the com- 

 munications between the Observatories of Cambridge and Quebec, 

 were completely successful, and the longitude of Quebec, as well as 

 those places already referred to, finally settled. 



The longitude of the Observatory as obtained by telegraphic signals, 

 and the longitude published ou the Admiralty Charts differ by no less 

 than fourteen seconds of time, and the other places whose positions 

 have been determined in a similar manner have a still greater difier- 

 ence. 



On the 29 bh October, I left Quebec for Ottawa, and on my arrival 

 put up at Mr. Doran's boarding house and went in quest of a site 

 for the transit instrument. On Barrack Hill there were several 

 blocks of limestone, around one of which I built a little Observatory 

 and had the telegraph wire brought there. The night of the 14th 

 November was beautifully clear, and the result of our night's work 

 most satisfactory. 



June 18th, 1858. I left Quebec for Three Elvers, and on my 

 arrival I accepted the kind invitation of Oliver "Wells, Esq., to make 

 his house my home, and immediately went in search of a place suit- 

 able for fixing the transit instrument. After some time I selected the 

 Barrack Square (then unoccupied) as the spot most suitable for my 

 purpose, as it was close to the Telegraph Office, and was also fenced 

 in, I felt myself secure from the intrusion of boys — the pest of 

 itinerant astronomers ; indeed I had not seen any since my arrival. 



As there was no rock in the neighbourhood, nor any thing suitable 

 for the support of the instrument, on the sandy foundation that exists 

 in the vicinity of Three Rivers, and as a very fine Roman Catholic 

 Cathedral was in the process of erection not far off", I went at once
