Part of the reason for the discrepancy was Pennsylvania's "over-elaborate" and sometimes "unintelligible" method of "ordering and purchasing supplies, equipment [and] furnishings, commonly called the 'per-foot rule' ".[36] Because the methods of measuring under the "per-foot rule" were not rigorously enforced, furnishing could be, intentionally, overpriced by the supplier. For example, a flagpole installed on the capitol roof was priced at $850; Berry estimated the value of the pole to have been only $150.[37] Other expenses included $1,619 for a $125 bootblack stand and $3,257 for a $325 "mahogany case in the Senate barber shop".[38]
