I wonder how that would fit in with the canon-launcher proposed in "The Begum's Fortune"? Wasn't that supposed to send a shell only one "orbit" of the Earth - back to Oregon and Frankville (or Stahlstadt). Wouldn't it still need to achieve escape velocity, even for a low- or sub-orbital "trajectory"?
The mathematics involved are way beyond me, but JT Maston might have managed it.
If it weren't for his mishap with lightning, he might have realized that the Kilimanjaro cannon of "Purchase of the North Pole" wasn't possible, much sooner.
This episode is integral to the argument I proposed at the Tampa meeting of the NAJVS, that JT Maston was also the character Professor James Moriarty in the Sherlock Holmes adventures.

  "and calculations have shown no cannon could be powerful enough to achieve escape velocity."

  Not true. Work has proceeded on this up through last century (maybe this century, but I'm not sure.

  Look at Gerald Vincent Bull. He was working with Iraq to develop such a cannon.

  Jules Verne proposed a giant cannon in his novel From the Earth to the Moon. However, such a sudden burst of acceleration would inevitably kill any passengers instantly, and calculations have shown no cannon could be powerful enough to achieve escape velocity.
