The head of the drum would have been required to be kept tight, so the marbles allow for the head of the drum to be adjusted during the ceremony. The leather drum head would have been heated over the fire to allow for stretching. The church house would have owned the drum kettle and the drum parts. The drum itself was a standard cast iron kettle of a particular size, and then they would have modified the kettle to suit their needs. Water drums and kettle production became an expensive trade over time. Glass marbles were the common item for use with stretching the leather deer skin hide across the top. Drum marbles and drums were only used during a peyote meeting.
