Nor is this book to be a scientific monograph on Apis Mellifica, Ligustica, Fasciata, Dorsata, etc., or a collection of new observations and studies. I shall say scarcely anything that those will not know who are somewhat familiar with bees. The notes and experiments I have made during my twenty years of beekeeping I shall reserve for a more technical work; for their interest is necessarily of a special and limited nature, and I am anxious not to over-burden this essay.
