mule-jenny

Of course it will make unemployed, and our sympathy will be invoked for dressmakers thrown out of work: that is the old argument against railways on behalf of coaches, against the mule-jenny, against every engine of human progress, and it is sheer barbarism.

So early as 1775, in England, Crompton's mule-jenny had superseded Hargreaves' spinning machine.

And what need to cram one's self till the age of twenty with all sorts of knowledge, then to fasten the threads of a mule-jenny or pick coal at the bottom of a pit?

To properly exploit the mule-jenny, engineers, builders, clerks, brigades of workingmen and workingwomen of all sorts, have been needed.
