The majestic giant and of the tiny seed that packages it

One of the smallest seeds has package within it the biggest living thing on earth - the giant sequoia tree. It grows over 300 feet high. Four feet above the ground its diameter may be 36 feet. One tree may contain enough wood to build 50 six-room houses. The two-foot-thick bark is flavored with tannin that repels insects, and its spongy, fibrous texture makes it almost as fireproof as asbestos. Its roots cover three or four acres. It lives over 3,000 years. Yet the seeds that a sequoia tree rains down by the millions are not much bigger than a pinhead surrounded by tiny wings. A puny man standing at a sequoia's base can only gaze upward in silent awe at its massive grandeur.
