Primrose Cumming (1915–2004) was a British writer of children's books.
Her writing career spanned over 30 years, and produced some fine examples of the pony book genre, combining accurate observation of human and equine with a certain wry humour. In her most sought-after title Silver Snaffles, Tattles is brilliantly observed: by turns tetchy and patient, he is the archetypal family pony who has long-sufferingly taught generations of children to ride; in contrast, Smug, the evil pony in Silver Eagle Carries On has a mind strictly her own:
“Smug, of course, had no intention of jumping anything, but she held upon the right course until the last second, when she adroitly stepped to one side.”
Primrose Cumming was equally good at human characters: the Silver Eagle Riding School series has Josephine, the brilliant, but irritating middle sister, alternately a torment and an inspiration to her elder sister Mary. Tabby and Martin Mead in The Wednesday Pony dream their lives away wishing their pony Jingo was a show hack, a racehorse or simply a Dream Pony before realising that they would have to go a very long way before finding a better pony than the one they have.
Primrose Cuming was the youngest of a family of two girls and a boy, and was born on the Isle of Thanet, Kent, in 1915 during the First World War. She was educated by a governess, who recognised her flair for writing. Her first story, about the travelling adventures of an ant, was published in Nursery World. She said:
“I found it tremendously exciting writing about the country things I knew, and being paid for it – even if I did collect piles of rejection slips, too!“ 
The first book Primrose had published was Doney (Country Life 1934), which reflected her love of ponies. She was, she said,
“so keen on riding at this time, that I used to steal out early in the morning and ride the farmers’ horses in the fields. Then I wrote a book about my friend’s pony, Doney, and sold it. With the money, I bought Black Jack – who was rather too spirited for a beginner. When I took him hunting, he broke his bridle and off I came – in front of the whole field. At last we got on better terms and we both made our names by jumping everything in his path. To feed Black Jack, I wrote more books about country life, drawing on my own knowledge and experience. I had several published by the time I was 21.”
The published dates of Primrose Cummings’ books make it likely that these were Spider Dog (1935), and perhaps Silver Snaffles, which presumably was accepted for publication by the time she was 21: it was published in 1936, when she was 22.
Primrose Cumming still wrote during World War II, but also did war work, working for a year on a farm. One day a bomber crashed in the same field as the sheep she was looking after, but she survived, and her experience on the farm led directly to her book Owl's Castle Farm. Later she joined the Auxiliary Territorial Service and served for the remainder of the war in an anti-aircraft battery. Between air-raids, she wrote The Great Horses. This is the only one of her books of that period which is not set firmly in her own experience: it is an historical fiction, tracing the experiences of a line of heavy horses over several centuries.
After the war, she had a temporary job as under-matron in a boys’ school. This was not a success, as she saw the boys’ side rather more easily than the masters’. She returned to her family home in East Sussex, and decided to stick to writing and gardening. Horses were by no means her only interest: she was an expert flower arranger, and exhibited at the local flower shows and the Chelsea Flower Show. The books she published in her later years were based less closely on her own experiences. After parting company with J. M. Dent in the late 1960s, Primrose Cumming carried on writing for D. C. Thomson & Co., the magazine publishers, on many subjects and also contributed short stories to several editions of The Pony Club Annual. She stopped writing in the 1960s, feeling that she was becoming out of touch with modern youth. Primrose Cumming died in 2004.
None of her books are currently in print, but Fidra Books republished Silver Snaffles, which appeared in late 2007.
