I have my work cut out for me withHemingway, since he used many type-writers: a gigantic Royal No. 10 desk-top with glass side panels from his earlyKey West days, an Underwood Noise-less that helped him fi nish For Whomthe Bell Tolls and fi le dispatches fromhotel rooms while he was a World WarII correspondent, and black matte Roy-als from the early 1940s—especiallythe Quiet DeLuxe and Arrow—he fa-vored while at Finca Vigía in Cuba.

You have another function g that takes a B and returns a C. You can compose them by passing the result of f to g. You have just defined a new function that takes an A and returns a C.
That clears that. Arrow A->B and arrow B->C are not necessarily the same arrow (function).
Okay, so what are we doing here? Category is a set (?) of objects with arbitrary functions between them. The only property that this needs to satisfy is one of transitivity.
