Caption: Eprouvette Mortars and Iron Guns
Additional Description: Early black powder was often inconsistent in its strength and had to be tested before being used. These three iron eprouvette mortars were used to test samples of new lots of artillery powder. Around the flagstaff base are four iron guns, filled with concrete and buried breechdown. As new cannon were introduced, many old ones were used as pier bollards, gate posts, or - as in this case - bases for flagpole cleats.
