Old Photos: Love My Tortoise

I have been creating blogs recently.  Actually only one seriously, focused in a cross-eyed way on the history of seed companies and the general gardener's use of purchased seeds.  But while I am crawling through the internet attics that tell the stories I keep stumbling over wonderful photos from the past!  To amuse friends, I started two that are cat and dog blogs, Good Dog! Snapshots from the 20th Century and Cat Smiles.   I am not sure why I started the main blog, only I was looking up stuff for myself and I wanted to share it; it seemed a waste to find cool bits and pieces then leave them in the attic!

That all said, what do I do when I find something I like so much I want to share it but it isn't in any of my categories?  As you have already guessed, the answer is to stick them here!

I love these two photos.  For no reason I can pin point, I think it is the the 1940s or early1950s...probably England.

If you have never read Gerald Durrell's My Family and Other Animals, give it a try. An enchanting memoir from a world renowned naturalist, focusing on his childhood on Corfu where his English family went to escape the grey and sneezes of England.

Maker Alert: Very Cool 1870s Weather Prediction Device

This 1870 home-made weather glass (shown below) looks like fun to try...but could I do it by shopping on Amazon for all the chemicals and the bottle?  And, not having taken chemistry, can I do it without poisoning myself?

The answer looks to be YES to both concerns.  The chemicals are used in cooking...and blowing up stuff.  That is kind of cool by itself!

As a licorice lover, the fact that one of the chemicals, sal ammoniac, is used in the Nordic countries in a salty licorice candy opened a new world of treats to me. (And, yes, Amazon has that, too :-)  You could kill yourself with the chemicals if you were really dumb or determined, but it seems highly unlikely. I found a 12 inch glass hydrometer test tube for sale that was the right shape to substitute for the fascinating bottle illustrated below.  I wonder what that shape bottle was made for in 1870.  

The only problem is the cost gets to about $ I am out.  Sheesh...I wanted to see the star shaped precipitate rising and falling with the weather changes!!!!  Time to start looking around for friends with a bit of this and that laying around...maybe someone cures meat with saltpetre. I have a tube already from aborted wine making...that gets it down to 40ish.  I think I need to retire to have the time to pursue all this.

The last question is - does it work?  No clue.
