L'exemplaire filmd fut reproduit grAce d la g6n6rosit6 de: Izaak Walton Killam Memorial Library Dalhoutie University Les images suivantes ont 6X6 reproduites avec le plus grand soin, compte tenu de la condition et de la nettetd de l'exemplaire filmA, et en conformity avec les conditions du contrat de filmage. Original copies in printed paper covers are filmed beginning with the front cover and ending on the last page with a printed or illustrated impres- sion, or the back cover when appropriate. All other original copies are filmed beginning on the first page with a printed or illustrated impres- sion, and ending on the last page with a printed or illustrated impression. The last recorded frame on each microfiche shall contain the symbol -^ (meaning "CON- TINUED "I, or the symbol V (meaning "END"), whichever applies. Maps, plates, charts, etc., may be filmed at different reduction ratios. Those too large to be entirely included in one exposure are filmed beginning in the upper left hand corner, left ^o right and top to bottom, as many frames as required. The following diagrams illustrate the method: Les exemplaires originaux dont la couverture en papier est imprimie sont film6s en commenpant par le premier plat et en terminant soit par la dernidre page qui comporte une empreinte d'impression ou d'illustration, soit par le second plat, salon le cas. Tous les autres exemplaires originaux sont film6s en commengant par la premidre page qui comporte une empreinte d'impression ou d'illustration et en terminant par la dernidre page qui comporte une telle empreinte. Un des symboles suivants apparattra sur la dernidre image de cheque microfiche, selon le cas: le symbole — ♦• signifie "A SUIVRE", le symbole V signifie "FIN". Les cartes, planches, tabHaux, etc., peuvent dtre filmds d des taux de reduction diffdrents. Lorsque le document est trop grand pour dtre reproduit en un seul clich6, il est filmd d partir de Tangle supdrieur gauche, de gauche 6 droite, et de haut en bas, en prenant le nombre d'images n^cessaire.
