Chabert's Mission / La mission du marquis de Chabert

English:

In 1750 the Marquis de Chabert, a French astronomer, was commissioned to go to North America to correct the maps of Cape Breton, Nova Scotia and Newfoundland. Chabert had to determine the longitude of Louisbourg but he also recorded observations on the stars and the moon, as well as the tides and the climate. Within two years of his return to France, the French Royal Academy published Chabert's book documenting his findings in Ile Royal (Cape Breton).




French:
En 1750 un astronome français, le marquis de Chabert, reçut le mandat d'aller en Amérique du Nord rectifier les carts du Cap-Brenton, de la Nouvelle-Écosse et de Terre-Neuve. Il devait non seulement déterminer la longitude de Louisbourg mais également effectuer des observations sur les étoiles et la lune, ainsi que sur les marées et le climat. Dans les deux années qui suivirent son retour en France, l'Académie Royale publia l'ouvrage de Chabert contenant sa documentation sur l'Île Royale (ou Île du Cap-Breton.

Observation in Île Royale / Observations à l'Île Royale

English:
Chabert and his assistant are portrayed at Grand Anse on the Strait of Canso, Cape Breton, in this 1753 engraving. Using a quadrant, they are calculating the exact time by the method of lunar-solar distances, in order to determine longitude. Inside the tent are a globe and a clock, and projecting from it is the barrel of a telescope. The yellow star below pinpoints their location on Chabert's map.
French:
Cette graveure de 1753 nous montre Chabert et son assistant à Grande-Anse sur le détroit de Canso, au Cap-Breton.

Canada's First Observatory / Le premier observatoire au Canada

English:
Canada's first observatory for viewing the planets and stars was built here in 1750. A well-constructed timber-frame cabin, the observatory had windows, doors, locks and board siding. The instruments included eight telescopes. Six were refracting telescopes with focal lengths between 3 and 18 feet. There was a Gregorian reflecting telescope with a focal length of 3 feet as well as a telescope for measuring angles. The observatory also had a seconds clock, terrestrial globes, map of the stars and an octant.

French:
Le premier observatoire astronomique au Canada fut érigé ici en 1750. Situé dans un édicule à ossature de bois bien aménage et muni de fenêtres, de portes, de serrures et d'un lambris en planches, il renfermait huit télescopes, dont six lunettes astronomique à distance focale d'entre 3 et 18 pieds. Il y avait également un télescope à réflexion d'une distance focale de 3 pieds, de même qu'un télescope de mesure des angles. L'observatoire refermait également un compte-secondes, des globes terrestres, de cartes de ciel et un octant.
