Impossible Performance on the Part of the Grass (bits from the archives)

Grass

In 1892, British electrical engineers of the Department of Telegraphs in Calcutta, as part of an exercise, buried a piece of india-rubber cable core treated to withstand attacks by termites. After six months, when the cable was dug up, engineers found grass growing through the cable. On 1 February 1893, P. V. Luke, a member of the Institution of Electrical Engineers, wrote the following in his letter to the secretary of the institution:

What at first sight appears to be an impossible performance on the part of the grass seems less so when you come to examine the hard, sharp, needle-like points which characterise the roots of this species of grass.*
