The worst thing about this sort of a head was that it did not keep well and was sure to spoil sooner or later. So Jack's main business was to grow a field of fine pumpkins each year, and always before his old head spoiled he would select a fresh pumpkin from the field and carve the features on it very neatly, and have it ready to replace the old head whenever it became necessary. He didn't always carve it the same way, so his friends never knew exactly what sort of an expression they would find on his face. But there was no mistaking him, because he was the only pumpkin-headed man alive in the Land of Oz. A one-legged sailor-man was a member of Ozma's council. His name was Cap'n Bill and he had come to the Land of Oz with Trot, and had been made welcome on account of his cleverness, honesty and good-nature. He wore a wooden leg to replace the one he had lost and was a great friend of all the children in Oz because he could whittle all sorts of toys out of wood with his big jack-knife. Professor H. M. Wogglebug, T. E., was another member of the council. The "H. M." meant Highly Magnified, for the Professor was once a little bug, who became magnified to the size of a man and always remained so. The "T. E." meant that he was Thoroughly Educated. He was at the head of Princess Ozma's Royal Athletic College, and so that the students would not have to study and so lose much time that could be devoted to athletic sports, such as football, baseball and the like, Professor Wogglebug had invented the famous Educational Pills. If one of the college students took a Geography Pill after breakfast, he knew his geography lesson in an instant; if he took a Spelling Pill he at once knew his spelling lesson, and an Arithmetic Pill enabled the student to do any kind of sum without having to think about it. These useful pills made the college very popular and taught the boys and girls of Oz their lessons in the easiest possible way. In spite of this, Professor Wogglebug was not a favorite outside his college, for he was very conceited and admired himself so much and displayed his cleverness and learning so constantly, that no one cared to associate with him. Ozma found him of value in her councils, nevertheless. Perhaps the most splendidly dressed of all those present was a great frog as large as a man, called the Frogman, who was noted for his wise sayings. He had come to the Emerald City from the Yip Country of Oz and was a guest of honor. His long-tailed coat was of velvet, his vest of satin and his trousers of finest silk. There were diamond buckles on his shoes and he carried a gold-headed cane and a high silk hat. All of the bright colors were represented in his rich attire, so it tired one's eyes to look at him for long, until one became used to his splendor.
