This poem interests me and looks fairly simple – let us consider one or two lines and see if we can explore some more deeply. Indeed, this is a poem about surfaces and depth with a number of words that suggest rest- abolish pace, slow, apart and torpor. There is too a general feeling for sculpture as is expressed in his remarks about stone and it’s weathering or erosion by water. Details about Stokes may be found at his Wikipedia entry where it states about his early writing;” In The Quattro Cento he characterized the intense Early Renaissance feeling for material and space as ‘mass-effect’ and ‘stone-blossom’. The stone—deeply respected as a medium – is, he said, ‘carved to flower’ thereby bringing to the surface the fantasies the artist reads in its depths.” Let us continue to dig beneath the surface of these lines.
There seems to be a general feeling of relief perhaps reflecting Stokes returning to Cornwall. The lines about outhouses and stone retrace unmeagre time seems somewhat demanding. Does this mean that such structures seem and suggest aeons of time? Meagre is a synonym for sparse. So this may mean that the scene implies the extensive nature of time. As Stokes studied philosophy, then it is quite possible that some sort of Bergsonian concept of time.{See https://www.bbc.co.uk/programmes/m0004s9w }
In the next line herd is somewhat unusual- maybe the light from the shining mica in the granite is being collected by the eye. It also is a homophone for heard which brings a whimsical feeling of synaesthesia together with the metal clang of time colliding with rhyme. In the next stanza there is hoard and heart which may be associated with the unusual word hurd, the coarse parts of flax or hemp that adhere to the fiber after it is separated. — called also hards. This sounds very much like the Golden Fleece and adds to the reference to the early Cornish tinners. A milksop is a person who is indecisive and lacks courage. Milksop can be a piece of bread dipped in milk. The flower might mean a milkwort or just a general term for any flower in a field which may have cows in it!
The word also brings to mind that Stokes was deeply interested in psychoanalysis and was in fact an analysand of Melanie Klein whose work focused around infantile phantasy at the breast. He was also a friend of Barbara Hepworth whom he brought to St Ives where he lived near The Cornish Arms pub with his wife Margaret Mellis, The feelings of support, skin texture and associated tactile imagery come out in the second section where closeness is increased by the use of our. This underlying emotion of support and nursing passivity brings to an end this interesting poem.
