The answer to that is Denotation.
The mood portrayed in John Muir's "The Calypso Borealis" can be described as first very gloomy and disparate and then to joyous and relief. At first, the narrator is very discouraged because he cannot find the Calypso flower that he wants. But when he finds it, he seems very joyous and as the passage says, he "cries for joy". This means that he had been waiting and searching for a long time. Muir also uses dramatic terms like choosing to place the Calypso as a lonely flower in the middle of a bog.
Hope this helps :)
The underlined verb is becoming because when you look at the is becoming you see that it is in present tense and active voice. The is carries the present tense and the becoming carries the progressive aspect.
