These Grants appear only in the diagram book, not the various Locomotive Data books from this same railroad. The EHS is said to reflect only the tube heating surface, but a straight calculation of the tube heating surface yields 72 sq ft less than the figure givenin the diagrams. Yet even in 1888, a firebox that small in a Ten-wheeler seems unlikely given that its minimum depth was 72".
All we can see is that the engines had a relatively large gap between the 2nd and 3rd driven axles to accommodate the firebox and that the driver diameter bespeaks a mixed-traffic service.
A long-stroke Vauclain compound Ten-wheeler, this was the only engine in its class. In 1906, the EJ & E sold the 32 to the Saint Paul & Des Moines, which renumbered it 62. The Chicago, Rock Island & Pacific bought the StP & DM in 1911 and changed its name to St Paul & Kansas City Short Line.
It was only then that the 62 was rebuilt with 18" x 26" cylinders and 63" drivers. the Rock Island took the engine onto its own stud and renumberd it 1163.
Five years after the EJ & E Ten-wheelers shown in Locobase 7293 came from little-known Grant Locomotive Works, a Paterson, NJ builder, that same small company supplied 5 more with 20 more fire tubes. The diagram shows only the tube heating surface and notes that they were discarded on 2-20-1916.
