UNITED STATES TESTS FIRST OF BIG NEW SEA-GOING SUBMARINES
The M-1 (SS-47) is shown on her trial trip off Provincetown, Mass., on 6 July. She is 230 1/2 feet long, with 21 1/2-foot beam. Her radius of action is 2,000 miles.
She is not as large as the German submarine Deutschland, now at Baltimore, whoso length is 315 feet, with a 30 foot beam.
It is actually an EB design L-class boat. The paper that originally published the photo misidentified it. The caption is wrong.

Tonopah 496k A MOTHER SEADOG GUARDING HER PUPPIES
This interesting photograph was taken within the Charlestown Navy Yard, where the United States submarine tender Tonopah (M-8) lies at anchor with her undersea charges, comprising submarine fleet No.3, of the North Atlantic fleet.

L-9/ L-11 873k AMERICAN U-BOATS BACK FROM THE WAR
After 15 months hunting of German U-boats in the Irish Sea, the flotilla of submarines shown above returned to the League Island navy yard at Philadelphia. The L-11 (SS-51), (third from left) had many desperate encounters with the enemy boats, including a fight below the surface with a Hun sub, which L-11 subsequently vanquished.
L-9 (SS-49) is the second boat to the left, along with two unidentified submarines, which I believe are L-2 (SS-41) at the far right & L-3 (SS-42) on the left.
