Under Governor Thomas Melville, 1864 to 1884, a numbering system was developed for the Sailors' Snug Harbor Cemetery. The numbering system made burials in the old cemetery obsolete. This called for a new burial ground, which was constructed just outside the old cemetery (see D. of two cemeteries).

The Snug Harbor Cemetery Map above shows where Plot 4 is relative to the entrance gate of the cemetery. There is a scale factor on the original Maps at Suny Maritime Archives. The distance to a particular plot could be measured on the maps, and by applying the scale factor, the position of the cemetary plot could be determined in the Snug Harbor Cemetery.
Plot four of the cemetery Map
Plot 4, Row 4, number 5 grave, means Plot 4 as above, and from the right go left 4. This puts us in column 1233. Then go up 5 for grave 5. This gives us a grave number of 1233 + 4 = 1237 on the cemetery map.
