The expedition sailed northward along the coast, and the most important halt was in the port of Callao. The ships were left under the necessary guard, and the members of the company established themselves for four months in the valley of the Rimac. The viceroy Francisco de Gil y Lemus received the officers and the scientists, but the festivities of the viceregal court did not prevent somewhat elaborate investigations in Peru. Haenke accompanied by the botanist Tafalla and the draughtsman Pulgar, went over the Andes to Tarma and visited Huanuco and the mines of Cerro del Pasco. Tafalla and Pulgar had been associated with the botanical expedition under Ruiz and Pavón, and after its return to Spain, they remained under orders from the government to continue their botanical investigations in Peru, and to make collections to replace those that had been lost at Macora. [Sidenote: Voyage northward and to the Far East] [Sidenote: Haenke leaves the expedition] Towards the end of 1790 Malaspina’s expedition continued its northward voyage, halting at Guayaquil, Panama, Acapulco, and advancing to the Strait of Fuca and into the Behring Sea. In the beginning of 1792 it entered upon the voyage across the Pacific, to the Philippine Islands and Australia, and, returning, arrived at Callao July 23, 1793. This long voyage was for Haenke a period of fatiguing and profitless idleness; and when the expedition started on its homeward voyage from Peru it was determined by Malaspina and approved by the viceroy that Haenke should be temporarily separated from the ships and go to Buenos Aires by way of Huancavelica, Cuzco and Potosí, for the purpose of continuing his investigations in botany and zoology. Luis Nee, another member of the scientific staff, was permitted to leave the “Atrevida” at Concepción in Chile, and proceed by land to Buenos Aires and meet the ships at Montevideo. But Haenke, on account of the great extent of his proposed journey, had permission to delay his arrival in Buenos Aires until October or November 1794. Nee complied with the stated requirements, rejoined the expedition at Montevideo, and returned to Spain. Haenke, on the other hand, failed to carry out the conditions under which he was permitted to cross the continent. Letters from him received by his companions at Montevideo announced that on account of the extent of his explorations, reaching to the territory of the Mojos and Chiquitos, he would be delayed beyond the time specified for his arrival in Buenos Aires, but that he believed he would be in Montevideo and embark for Europe in the early part of the following year.
