"There is a difference between Peter and Peter."-Cervantes: Don Quixote."Spain is a contradiction," was the parting word of the Rev. William H. Gulick, the honored American missionary whose unwearied kindness looked after us, during the break in official representation, more effectively than a whole diplomatic corps. "Spanish blood is a strange mezcla, whose elements, Gothic, African, Oriental, are at war among themselves. You will find Spaniards tender and cruel, boastful and humble, frank and secretive, and all at once. It will be a journey of surprises."We were saying good-by, on February 4, 1899, to sunshiny Biarritz, whither Mrs. Gulick's school for Spanish girls had been spirited over the border at the outbreak of the war. Here we had found Spanish and American flags draped together, Spanish and American friendships holding fast, and a gallant little band of American teachers spending youth and strength in their patient campaign for conquering the Peninsula by a purer idea of truth. Rough Riders may be more pictorial, but hardly more heroic.
