Revolution in the mailbox: typewriters and border collies

A gratifying volume of letters, cards, and longer typescripts have been reaching me recently. Among them is a letter from a recent recruit to the insurgency. 

He includes an extensive meditation on typewriting and typewriters.

I was especially surprised and delighted to read this passage on the agency of typewriters:

The simile struck me because there's a new addition to my household: Della, a 10-week-old border collie. She's sweet, inquisitive, and playful. Border collies grow up to be so smart that I fully expect her to beat my words per minute—if only I can find a typewriter whose keyboard is adapted to a dog's paws.
