I am having trouble finding an example of alliteration in John Steinbeck's "Cannery Row".I can find imagery, personification, and even polysyndeton, but I cannot locate an example of alliteration!
You are referring to Cannery Row by John Steinbeck so do take care with the spelling as that will hinder your progress when you look for references.
Steinbeck attempts to reminisce in this novel, rather than focus on the difficulties of the Depression:
a time when men survived without money, on companionship, good intentions, and kindness
Steinbeck approaches his story in a way that draws the reader in to his world whilst being both descriptive and realistic. He uses various devices to ensure that the message is kept simple and there is no attempt to introduce a deeper connection; save to say that all Steinbeck's works reflected his stance on God and he is obviously most famous for "Grapes of Wrath" (which followed Cannery Road) and "East of Eden." This simplicity renders Cannery Road as one of his less popular works.
Alliteration can be found when Doc, as a Marine Biologist, is busy collecting :
..fantastic with hurrying, fighting, feeding ... from frond to frond... Starfish squat over mussels and limpets, attach their million little suckers ....with incredible power until the prey is broken ... And then the starfish stomach comes out ..... skirts waving like the dresses of Spanish.
