It is generally stated that the first Floral Dial, or clock, which showed the time by the opening or shutting up of blossoms throughout the day, was a fancy or invention of the great Swedish naturalist, Linnæus. But there is a distinct allusion to this poetical measurement of the "fleeting hours" in Marvell's poem on "The Garden:"—

"How well the skilful gardener drew

By flowers and herbs this dial new!

Where, from above, the milder sun

Does through a fragrant zodiac run;

And, as it works, the industrious bee

Computes its time as well as we.

How could such sweet and wholesome hours

Be reckoned but with herbs and flowers?"

Whether the idea first occurred to Englishman or Swede, poet or botanist, matters but little; it is a graceful, a suggestive, a beautiful idea, and might well be reproduced in some of our large public gardens.
