The Bureau of Standards did not have the statutory authority to enforce compliance with weights and measures laws. These laws were, after all, state laws. But the Bureau could direct public attention to the problem through exposure. The Progressive Era saw muckraking journalists such as Lincoln Steffens and novelists such as Upton Sinclair expose the corruption and greed associated with the new industrial economy. Between 1909 and 1911, the Bureau did some muckraking of its own, sending inspectors to every state in order to test scales, weights, and dry and liquid measures --a much larger investigation than the one launched in 1901. Reporters covered the weights and measures crusade with zest, motivating several states to enact a model weights and measures law proposed by the Bureau. A Bureau proposal to require that the net weight, measure, or numerical count of contents be printed on sealed packages was accomplished by a 1913 amendment to the Pure Food and Drug Act (1906).
