What message does The Call of The Wild reveal about the past?

The Call of the Wild is a story of transformation in which the old Buck has to adjust to harsher realities of life where survival is only imperative.

Explanation:

So all and all he has to get better with his surroundings and make the transformation with his survival skills in order to survive.

Side bar: The moral of it is to follow your instincts. And although Buck is loyal to his owner he follows his gut instead.

covert: hidden or secret

candid: truthful and straightforward

what i get from these phrases is covert means undercover or underground and that's where the flower is in april. on the other hand, may is the month where flowers start to bloom and thats the reason why candid is being used as a word to describe the blossoming period of a flower.

hope this answer you.
