This year (1910) the party was made up of Mr. Cameron Forbes, the Governor-General of the Philippine Islands; Mr. Worcester, Secretary of the Interior; Dr. Heiser, Director of Health; Dr. Strong, Chief of the Biological Laboratory; Mr. Pack, Governor of the Mountain Province; and of two officers besides myself, Captain Cootes, 13th Cavalry, Aide de Camp to the Governor-General, and Captain Van Schaick, 16th Infantry, Governor of Mindoro. General Sir Harry Broadwood, commanding His Majesty's forces at Hong Kong, had been invited, but at the last moment cabled that his duties would prevent his coming. Unless he reads this book he will never know what he missed! As we passed through the various sub-provinces their respective governors and one or two officials would join us and ride to the boundary. On account of the difficulties of supply and transportation, we were requested to bring no _muchachos_ (boys--i.e., servants), so we had to shift for ourselves. Our baggage was very strictly limited; each man being allowed two parcels, one of bedding, and the other of clothes, neither to be more than could be easily carried on the back of a single _cargador_. Mr. Worcester took along for the whole party an ingenious apparatus of his own contrivance for boiling drinking-water, as all streams in the Philippines at a level lower than 6,000 feet have been found to contain amoebae, [7] the parasitic presence of which in the intestines produces that frightful disease, amoebic dysentery. We were especially desired to leave our revolvers at home, and had no escort.
