"In response to Mr. Howe's enquiry (Bulletin No. 16, p. 7) I can make the following amendments from examples in my collection:
BERBICE RAILWAY. I have this mark on S.G.253 dated 13 DEC 1907 which is 10 months earlier.
The normal type consists of name at top, B. GUIANA at the bottom and date in three lines in the middle.
EAST COAST RAILWAY. In a similar type to the one listed above I have a T.P.O. E.C. RAILWAY dated 16 SEP 1899 which is 2 months earlier."
"I observe in Bulletin No. 16 that Mr. F. G. Howe asks for early dates of these T.P.O's and on reference to my collection I find I have the following:
| Demerara Railway | 18.10.1884 |
| East Coast Railway | 20. 6.1899 |
| Essequibo Steamer | 25.10.1881 |
| Massaruni Steamer | 2.12.1892 |
| West Coast Railway | 18.11.1903 |
Regarding 'North West Str.' I have found this to be very scarce and only possess one example dated May, 26th 1898."
