But the rejoicings to which these victories gave rise were of short duration. The early frosts of 1691 had injured the crops, and the country was menaced with famine. On the 9th of June, in this year, the rain fell in torrents, and, accompanied as it was by hail, destroyed the grain that was cultivated not only around the capital, but also in many of the best agricultural districts. The roads became impassable, and many parts of the city of Mexico were inundated by floods from the lake, which continued to lie in the low level streets until the end of the year. Every effort was made by the authorities to supply the people with corn,--the staff of life among the lower classes,--and commissaries were even despatched to the provinces to purchase grain which might be stored and sold to the masses at reasonable prices. But the suspicious multitude did not justly regard this provident and humane act. They imagined that the viceroy and his friends designed to profit by the scarcity of food, and to enrich themselves by the misery of the country. Accordingly, loud murmurs of discontent arose among the lower classes in the capital, and on the 8th of June, 1692, the excited mob rushed suddenly to the palace of the viceroy, and setting fire not only to it but to the Casa de Cabildo and the adjacent buildings, destroyed that splendid edifice together with most of the archives, records and historical documents which had been preserved since the settlement of the country. A diligent search was made for the authors of this atrocious calamity, and eight persons were tried, convicted and executed for the crime. The wretched incendiaries were found among the dregs of the people. Many of their accomplices were also found guilty and punished with stripes; and the viceroy took measures to drive the hordes of skulking Indians who had been chiefly active in the mob, from their haunts in the city, as well as to deprive them of the intoxicating drinks, and especially their favorite _pulque_, in which they were habituated to indulge. The crop of 1693, in some degree, repaired the losses of previous years, and in the ensuing calm the Conde de Galve commenced the rebuilding of the viceroyal palace. The property destroyed in the conflagration in June, 1692, amounted in value to at least three millions of dollars. * * * * * In this year, the viceroy, who was anxious for the protection of the northern shores of the gulf, and desirous to guard the territory of Florida, from the invasion or settlement of the northern nations of Europe, fitted out an expedition of expert engineers to Pensacola, who designed and laid the foundations of the fortifications of this important port. Three years afterwards, before the termination of his command in New Spain, Galve had the satisfaction to despatch from Vera Cruz the colony and garrison which were to occupy and defend this stronghold.
