 | | Two years previously, Hassler had been asked by the President to compare the weights and measures in use at the principal customhouses, and now, in 1832, the Coast Survey and the Nation's metrological work were combined in the person of Hassler. |
 | | Finding large discrepancies in the weights and measures in use, Hassler obtained the approval of the Secretary of the Treasury to construct standards of length, mass, and capacity for distribution to the customhouses. |
 | | Under Hassler and his successors' supervision and with the authority of the 1836 joint resolution, OWM continued to construct troy and avoirdupois weights, yard measures, half bushels, gallons, half-gallons, quarts, pints, and half-pints. |
