Can anyone help me find where this verse came from

[Heather Turner]

Out of the gloom and the grit and the grey
out of the fog and the bold
you shall come to a land where the peacocks play
in a garden of green and gold
where big blue butterflies haunt the glades
and the snow white egret dreams
where rubies are found by nut brown maids
wading in orange streams

I lived in Burma approx 1953 and when I came to leave a friend wrote the above verse in my autograph book.
Any help would be greatly appreciated, Thank you
Heather.
