Just back from his first trip to Cuba, he was keen to share his enthusiasm for the "Pearl of the Antilles" with his fellow Montrealers: he gave a lecture entitled "Under the Cuban Sun" (in French) at the Botanical Garden:
From a collection of 600 Kodachromes taken during a four-month stay, I will show only a few of the most characteristic ones that may be of interest for Biology in the broader sense, focusing especially on plants, people and the bonds between people and plants.
Marie-Victorin used this glass-slide projector during the lectures he gave at the Montr?al Botanical Garden ? probably including the one he called "Under the Cuban Sun", and another that he later wrote about to Brother L?on:
Here in the Botanical Garden auditorium I gave a lecture called: "Some Treasures from Tropical Gardens". It was fully illustrated with Kodachromes. I can assure you that on a large screen, with a thousand-watt lamp, it's fabulous to see the Triplaris americana, Spathodea nilotica, Bougainvillea, Datura arborea and other marvels that you have all become blas? about and can no longer appreciate.
Besides the slides, the black and white photographs that Marie-Victorin took in Cuba were all printed and placed in eight photo albums.
