It's interesting that you could get all the way to Hawaii quicker than you could get to the west coast of South America. There doesn't seem to be a technical impediment here, I guess there just weren't scheduled ship routes at the time?
I suspect that it simply took longer to sail around Cape Horn in South America (a dangerous and time-consuming journey) to get to the west coast of South America than it did to sail to New York, take a train to California, and hop on a ship to Honolulu.
I had assumed that a trip to Hawaii would transit the Panama Canal, but you may be right about the route. WP says the canal opened in August 1914, so it might not be included here. I wonder how different a map made just a few years later would be.
