Post Cards with Hidden Messages

Over the years I have collected a variety of post cards carrying some kind of hidden or coded message [See HERE for details]

The above card, showing Berkhamsted School, carried the message:

A small portion of the "River Spey" was picked up this morning, close to the "April Flight" & is at present in safe custody. Will transfer it to yours in a day of so. Hope you got home safely. Yours ever J.B.

where "River Spey" and "April Flights" seem to have some hidden meaning.- can anyone suggest what the message may be about. Are the words anagrams - or do they represent something everyone would have known about when the card was posted in 1904

An 18th Century Mausoleum at Watford carries a hidden message

Post Cards

The postman can easily see what you have written on a postcard, and lovers often found ways of coding a message. Some wrote in shorthand, while others used special codes. The sender of this card, showing an interesting mausoleum which doubled as an ice house, uses a very simple device to obscure the quite innocent message it carried.

Watford

For more information on the card see

Thomas MEADOWS' Mausoleum at Watford, 1781

and for more on how messages were concealed see Hidden Messages

A Post Card with a coded message

This card (which shows Apsley Church on the other side) was posted in Hammersmith on 30th April 1906 to Miss Evelyn R Allen (born 1892) of 74 Elm Grove Road, Barnes, S.W.

Can anyone break the code?

Yet another card with a coded message. Can you read the message? 
Note the angle of the stamp.

Hidden Messages - The Shorthand Message

Kathryn has replied to my earlier post (Can anyone read shorthand?) with a translation - which is not very secret - but reminds us that many people exchanged post cards merely to add to each other's collections. (Perhaps a bit like the way some people now collect friends on Facebook!)

Dear Mr Uphill  Thank you for your lovely postcard of Dorchester. You said I think that you liked pictures of churches. Have you ever seen a photo of this church before? I myself think that houses would be such a delightful collection of postcards. You said that you like foreign correspondents best,  I think everywhere today,  I have a correspondent in China, Malta, Gibraltar and in America, and find it very interesting indeed. Yours sincerely 

So my Hidden Messages page now has two examples - but I would love to find some more on Hertfordshire cards. Definitely some used number codes (1=A, etc - or even more sophistcated). 

Can anyone read shorthand?

I have just got a postcard of Baldock church, posted in Cornwall to someone in Dorset and before I properly document it I would like to know what the message says. I assume this is standard shorthand.

I have posted the complete card, which shows a picture of Baldock Parish Church, on the Hidden Messages page.
