He was involved in a number of other cotton mills. Not long after spinning began in New Lanark, Dale built a new mill in Blantyre and once again, there was a school for the apprentices. He sold the venture to James Monteith in 1792. The mills are better known nowadays as the birthplace of missionary David Livingstone. In 1788, Dale went into partnership with Claud Alexander of Ballochmyle (former Paymaster for the East India Company) in a spinning mill in Catrine in Ayrshire. Dale was heavily involved in the design of these mills and within a few years, some 1,300 people were employed. Once again there were apprentice (but no pauper) children and a proper school was provided. He remained involved with the business until 1801 when the mills were sold to James Finlay. Dale’s interests spread far and wide. In partnership with a number of others, he opened a small mill in Spinningdale in Sutherland. This was more a charitable effort than anything else. The aim was to provide work and relieve famine, distress in the area and also to stem the tide of emigration from the Highlands. Dale remained involved long after all the others had left and continued to finance it until two years before his death. The mill burned down a year later.
