Old Cornish Poem

I have another one to upload at some time. I wonder if trepolpen can advise on the author of this?

Canon James Sims Carah was the Cornish Bard named Gwas Crowan, meaning Servant of Crowan.
He was vicar of Penponds Church , Camborne, from 1896 to 1935, and first President of Camborne OCS. Made a Bard in 1928.
