Sebastian John Alexander Brown was the littlest boy in his home town."" And like many small boys it was important for him to prove that he could do big things. It is a wistful but determined Sebastian who sets off in quest of a dragon--a very agreeable, drowsy dragon whom, ultimately, he subdues. Maxine Kumin finds within the restriction of the couplet ample room for lilting irregularity. Her verse reads naturally conveying the full humor and pathos of Sebastian's plight. Many snatches of this will find their way into the child's memory.
