Paving Stones of Grass.

Paving blocks made of meadow grass are now manufactured. Their inventor was a clergyman, and the meadow grass, impregnated with oil, tar and resin, is pressed into blocks and finally bound with iron straps. The advantages claimed for these blocks are that they, are noiseless and elastic, resist the wear well and are impervious to heat and cold.
