What type of images are used in the poem "Cargoes" by Masefield?

The images in "Cargoes" are mainly visual. Almost all
suggest colors and textures, though some also suggest aromas (cedarwood, cinnamon) and
some suggest smells (smoke-stack, coal). The blazing colors of stanza 2 are preceded by
somewhat less color in stanza 1 and followed abruptly by an almost unrelieved
gray-brown-black palette of color in stanza 3. There is little stress on auditory
images, except that one may imagine the apes chattering and the peacocks calling.
"Cargoes” is a fascinating poetic image-picture (analogous to a triptych in art), in
which specific things are almost graphically rendered. Readers respond readily to
Masefield’s language. Indeed, the poem’s great value is that its diction, being so real
itself, leads naturally into a general discussion of degrees of reality as represented
by language.
