Here is a duck:

Roman equivalent, the letter Z. In the motion pictures this bird, a somewhat z-shaped animal, suggests the finality of Arcadian peace. It is the last and fittest ornament of the mill-pond. Nothing very terrible can happen with a duck in the foreground. There is no use turning it over. It would take Maeterlinck or Swedenborg to find the mystic meaning of a duck. A duck looks to me like a caricature of an alderman.

Here is a sieve:

Roman equivalent, H. A sieve placed on the kitchen-table, close-up, suggests domesticity, hired girl humors, broad farce. We will expect the bride to make her first cake, or the flour to begin to fly into the face of the intrusive ice-man. But, as to the other side of the cardboard, the sieve has its place in higher symbolism. It has been recorded by many a sage and singer that the Almighty Powers sift men like wheat.

Here is the picture of a bowl:

Roman equivalent, the letter K. A bowl seen through the photoplay window on the cottage table suggests Johnny's early supper of bread and milk. But as to the white side of the cardboard, out of a bowl of kindred form Omar may take his moonlit wine, or the higher gods may lift up the very wine of time to the lips of men, as Swinburne sings in Atalanta in Calydon.
