Book excerpt: Excerpt from The Philosophical Magazine and Journal, Vol. 51: Comprehending the Various Branches of Science, the Liberal and Fine Arts, Agriculture, Manufactures and Commerce Dear Sir, - If you consider the following observations on flax-steeping Worth of a place in your valuable Magazine, I will thank you to insert them. They are the substance of answers furnished by me to inquiries made upon that subject by G. Thomson, Esq. of the Trustees Office, Edinburgh. When in Dumbartonshire in 1801, reducing to practice the process of bleaching by steam, I had a few spindles of yarn given me to prepare for weaving. There was in the sleekness of the thread something that attracted my attention. Having soaked it over-night in warm water to prepare it for steaming, I was much surprised at the change of colour, and the quantity of colouring matter dissolved in the water. It was then washed, wrung, and soaked in a weak alkaline ley, and laid for steaming over some brown linens. After steaming the usual time, the covers were taken off. The yarn was found to have attained a degree of whiteness I never had before observed under similar circumstances. It was washed in the stream so long as any colouring matter came from it, and laid to the grass for two days. I remember well the colour was such as to impress me with a strong belief that some great and important discovery might be the result of accurately following up the process this flax had gone through; and I immediately made inquiry of the lady to whom the yarn belonged, who informed me she had it from a person she named, in the neighbourhood: to this individual I made the same application, and traced the yarn to have been purchased at a Kilmarnock fair. Here the matter rested till the next season of lint pulling. I had a particular wish to trace if possible the matter to its source, and conceived the best plan would be to traverse that part of the country, from Stirling towards Kilmarnock.
