I cannot find the "rift"; still it may be there. What the poem seems to
say is, that a person would be coldly ungrateful who could consent to
count and consider little spots and flaws in such a warm, great,
satisfying sun as Harriet is. It is a "little rift which had seemed to

little rift which perhaps had never existed. How does one do that?
How does one see the invisible? It is the fabulist's secret; he knows
how to detect what does not exist, he knows how to see what is not

pretty woman, hour after hour, and responding like a tremulous instrument
to every breath of passion or of sentiment in the meantime, that man is
