This is an essay collection broken into four parts: Biology, chemistry, physics, and astronomy. As the subtitle says, it's a brilliant overview of the exciting realms of science. The title invokes the image of viewing science from above, to get an overview of it, and in the introduction Asimov likens science before 1800 to a well-managed orchard. After 1800, it's overgrown and even though there's still an underlying order to it, each wanderer through the orchard only gets to see a small part of it.

"So I have here a collection of essays with little internal unity. They are glimpses, here and there, of the orchard of science, as viewed from a height."
