How vain it is to sit down to write when you have not stood up to live! Methinks that the moment my legs begin to move, my thoughts begin to flow, as if I had given vent to the stream at the lower end and consequently new fountains flowed into it at the upper. A thousand rills which have their rise in the sources of thought burst forth and fertilize my brain. You need to increase the draught below, as the owners of meadows on Concord River say of the Billerica Dam. Only while we are in action is the circulation perfect. The writing which consists with habitual sitting is mechanical, wooden, dull to read.
