One of the most important modifications in the stocking-frame was that which enabled it to be applied to the manufacture of lace on a large scale. In 1777, two workmen, Frost and Holmes, were both engaged in making point-net by means of the modifications they had introduced in the stocking-frame; and in the course of about thirty years, so rapid was the growth of this branch of production that 1500 point-net frames were at work, giving employment to upwards of 15,000 people. Owing, however, to the war, to change of fashion, and to other circumstances, the Nottingham lace-manufacture rapidly fell off; and it continued in a decaying state until the invention of the bobbin-net machine by John Heathcoat, late M.P. for Tiverton, which had the effect of at once re-establishing the manufacture on solid foundations.
John Heathcoat was the youngest son of a respectable small farmer at Duffield, Derbyshire, where he was born in 1783. When at school he made steady and rapid progress, but was early removed from it to be apprenticed to a frame-smith near Loughborough. The boy soon learnt to handle tools with dexterity, and he acquired a minute knowledge of the parts of which the stocking-frame was composed, as well as of the more intricate warp-machine. At his leisure he studied how to introduce improvements in them, and his friend, Mr. Bazley, M.P., states that as early as the age of sixteen, he conceived the idea of inventing a machine by which lace might be made similar to Buckingham or French lace, then all made by hand. The first practical improvement he succeeded in introducing was in the warp-frame, when, by
