rubber should not be used as a synonym for “crane”; nor rubber-necking for “craning the neck.” These terms are slang which have been derived from rubber-neck, a playful expression said to be current among the children of Nova Scotia and used by them on April 1st instead of the more common “April fool.”

The Primary Use of Liquid Rubber to Plants

The grubs of many beetles live in wood, upon which they feed. This probably gives a clue to the primary use of the important commercial substances india-rubber and guttapercha, which are the dried sticky juices of various shrubs and trees growing in hot climates. Beetles of the wood-boring kind, which seek to pierce and lay eggs in such plants, are liable to be snarled and killed by the viscid fluids which ooze out.

Arums, and various other plants, ward off the attacks of snails and slugs in a rather curious way The outer parts of their stems and leafstalks contain bundles of excessively sharp crystals (raphides ), composed of oxalate of lime. These pierce the soft mouths of snails and slugs like so many needles, conveying a lesson which usually needs no repetition.
