The _ayuda de costa_, of which we hear so much, was either a more or less definite increase of salary, or a special gift for cause, or else a simple _merced_ or benevolence. While the salary was a matter fixed and due, the ayuda was always to a certain extent arbitrary and was used as an incentive to compel the performance of duties regarded as onerous. We see the germ of it in Torquemada's instructions of 1485, prohibiting fees and bribes, for the king provides a reasonable support for all and in time will give them _mercedes_.[736] An advance is marked in the Instructions of 1498 where, after specifying salaries, it is added that the inquisitors-general, when they see that there is much labor or necessity, can grant such ayudas de costa as they deem proper.[737] Accordingly about this time, while we find no regular ayudas given, there are constant examples of special ones, sometimes of large amounts, granted for the most varied reasons, of which two or three instances will suffice. Thus Ferdinand, April 30, 1499, in ordering the payment of the salaries in Seville, includes 40,000 maravedís of ayudas de costa for one of the inquisitors, but none for any one else. August 10, 1502, Juan Royz, receiver of Saragossa, is given an ayuda de costa of 10,000 sueldos to meet expenses incurred in illness and, on September 27th, an official of Seville is gratified with 20,000 maravedís to help him in his marriage.[738] It cannot have been long after this that the ayuda de costa was becoming a regular annual payment as an increment of the salary. December 3, 1509, an order for the payment of arrears to Diego de Robles, fiscal of the Suprema, speaks of there being due to him his ayuda de costa for 1506 and half of 1507, at the rate of 20,000 maravedís per annum. The first formal statement of it as a settled thing, that I have met, occurs in this same year 1509, in the list of salaries made out for the attempted Inquisition of Naples, where the ayuda de costa is designated for each official. It varies from a little over half the salary to considerably below that proportion and for two of the officials there is none. Yet it was not a universal custom for, in the salaries assigned to the Sardinia tribunal, September 10, 1514 there is no allusion to ayuda de costa.[739] That the custom, however, was gradually establishing itself as a substantial addition to the regular salaries is deducible from formal lists of the ayudas de costa of the Suprema and the Valladolid tribunal in 1515 and, by this time, it may be regarded as fairly established, although innumerable special grants continued, such as one of 75,000 maravedís, June 30, 1515, to Alonso de Montoya, notary of the Seville tribunal, to assist in his marriage.[740] Confiscations, at the time, were fruitful, and the laborers were not deprived of their share in the harvest, if only to stimulate their industry. Reimbursements of travelling and other expenses also frequently took the
