[That which had been] the physical probability of conformity of this construction [with the standard of Castilla] was rendered certain with remarkable exactness. Commission was given by the cabildo of this city that twenty-five steelyards should be sent from the kingdom of Nueva España; and, these having been brought hither at the time when the aforesaid steelyards and the weights, both large and small, were already made, [the cabildo] proceeded to make the comparison [between these and those] with judicial solemnity and the assistance of experts. This transaction having been completed with the exactness which its importance rendered urgent, the two sets of steelyards were found to agree so closely that it appeared that in those sent from Nueva España the scales were balanced by the weights made in Manila, or that these were the regular weights for the said steelyards!... This measure, be it worthy of record, began with the benefit to the common people of these islands in the suppression [33] of the da-chens, or Chinese steelyards; for the easy and continual fraud therein was computed by an official as being, in the limits of Manila alone, more than thirty thousand pesos a year--an evil so deeply rooted that few persons supposed that it could be remedied. So far did this go that the Marquès de Torre-Campo, then governor of these islands (whose prudent moderation was always honored), at the time when permission was asked from him for the publication of the proclamation by which the new usage was established and the old one prohibited, made very sententious remarks expressing his opinion that the said effort would be useless on account of the difficulties which, he inferred, would obstruct its effectiveness. But experience proved that he was mistaken; for in twenty-four hours [from that time] it would have been difficult to find any Chinese steelyard, if search had been made. It appears from the original acts--and these have been furnished to us for this relation, which in everything punctually follows and refers to them--that before reaching this last step, the publication of the prohibition of Chinese weights, the authorities caused to be made as large a number of properly regulated steelyards as the shops and guilds which use them might reasonably be expected to need. Then the Chinese were notified that the da-chens which they used should be brought forward; these were retained [by the authorities], and Castilian steelyards were given [in place of them], with printed instructions for observance by those who used them; and steelyards for the use of the public were set in various places, with trustworthy persons [in charge], who could instruct persons of little understanding. And it is generally known that, although this was a matter of so serious tendency, and included every class of persons, not the slightest disturbance arose; for all knew its importance, and in order to enjoy the convenience [of the new weights] submitted to
