Maybe because I've never been lucky enough to live in a house that was of an age (or in a location) for a milk door or milk chute, I've always had a fascination with those tiny little double doors that open into the kitchen or near the front door. Those little passages opened on the outside, for someone to put the milk/butter/cheese/love note in, and then a little door on the inside would open for one to retrieve said treasure.
Why did we stop doing that? Well, probably because--sadly--no one has milk delivered anymore (that's a whole 'nother post). But what we do today like crazy is order stuff online. Imagine if the postman or UPS guy or gal could pop our packages right into a safe, dry, secure little trapdoor instead of leaving a note for later delivery or leaving the package out in the rain/snow/sun/full view of mean people and/or dogs.
Sounds like a plan to me! If only I could go back in time and order one of these little beauties as seen in this "For Better Housekeeping" column in my August 1928 Better Homes & Gardens magazine:
The little last part of the article, which I have not included here, notes: "Do you sometimes wait at home for packages to be delivered, or worry about the milk that is delivered early in the morning? This cast iron package receiver can be placed in any house, old or new, in a wall thickness of from 5 to 14 inches. The deliveryman places his packages in the compartment and closes the door, which locks automatically. At your convenience, you remove the deliveries from the inner door and then pull a chain which again unlocks the outside door for more deliveries." What's not to admire there?
Also, check out this Flickr pool of milk door pics. They're cute. They're handy. Why'd we stop doing that?
