Hello, I'm Alex Cohn. I wanted to let you know that I reverted one of your recent contributions —specifically this edit to Health measures during the construction of the Panama Canal— because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help Desk. Thanks. Alex Cohn (let's chat!) 05:34, 28 October 2018 (UTC)
