We with our interest in mushrooms seized on the Mexican opportunity, and for years have devoted the few leisure hours of our busy lives to the quest of the divine mushroom in Middle America. Little by little the properties of the mushrooms are beginning to emerge. Each kind has its own hallucinogenic strength, and if enough of one species be not available, the Indians will mix the species, making a quick calculation of the right dosage. The curandero usually takes a large dose and everyone else learns to know what his own dose should be. It seems that the dose does not increase with use.
Some persons require more than others.
An increase in the dose intensifies the experience but does not greatly prolong the effect. The mushrooms sharpen, if anything, the memory , while they utterly destroy the sense of time . On the night that we have described we lived through eons. When it seemed to us that a sequence of visions had lasted for years, our watches would tell us that only seconds had passed. The pupils of our eyes were dilated, the pulse of ran slow.
