Extra fees may be charged from time to time by the Organisers, separately, but
with the approval of the Executive Committee, for any loss on courses or demonstrations but these extras are to be paid only by those members who have signified their intention to participate in such courses. Failure to attend any such course, after implicit notification to do so, shall specifically not release any Member from obligation, unless three weeks notice in writing to the Honorary Secretary of inability to effect such course, has been given.
