Congress Passes the Selective Service Act of 1917 and the Wyoming Guard gets the word

On this day, in 1917, Congress passed, finally, a much debated selective service act, ushering in a new era of "the draft".

The bill passed was massive and covered a plethora of topics.

At the same time, the mobilized and mobilizing Wyoming National Guard got the news that it would be taken into Federal service in July.

The odd thing about this is that the National Guard in Wyoming, and pretty much everywhere else, had been called out just as soon as war was declared.  But the government did not Federalize it right away.  Another example of how things were quite a bit different in World War One as compared to World War Two.
