How does E. B. White use imagery in One Man's Meat?

Imagery:

"I got a letter from a lightning rod company this morning trying to put the fear of God in me, but with small success. Lightning seems to have lost its menace. Compared to what is going on on earth today, heaven's firebrands are penny fireworks with wet fuses."

"While the old wars rage and new ones hang like hawks above the world, we, the unholy innocents, study the bulb catalogue and order one dozen paper-white Grandiflora Narcissus (60 cents) to be grown in a bowl of pebbles. To the list that my wife made out I have added one large root of bleeding heart, to remind us daily of wounded soldiers and tortured Jews."

"One of the phenomena of the war is the news coverage. In a sense the American people are a bit overtrained on this strange concentrated diet. Body and mind adjust to almost any sort of stimulus; we compensate physically for the news, just as we do for the speed of a motor car in which we are riding, until at last it seems as though the car is not in motion at all, and as though there is no news, not really."
