Anyone who is worth his salt is fired with the desire to add to the sum of human knowledge. That is one of the basic principles of our lives. For all such there is a vast field of useful work in the science of Aeronautics, provided they have sufficient determination and grit. It is to these I am speaking to-night, and it is my sole purpose to endeavour to direct interest in research Work by showing how easy it is to construct simple apparatus with little money. I propose afterwards to describe a few diverse experimental researches made with such an apparatus. Needless to say, it will be a real pleasure to me to give any assistance or advice I can to all who may decide to instal such apparatus. The greater the number of experimenters at work, the faster will our knowledge proceed, and so long as the work is done it matters little whether it is you or I who do it.
