But lead must be themetal if sulphuric acid, no matter in how small quantity, is usedin the water. It is generally resorted to by the men in sizingwool hats, as it facilitates the felting operation. This acid(vitriol), having no affinity for lead, does not affect the kettle, whileit would soon eat the one of copper through. Care, however, mustbe taken that no stone be let fall into the water of the lead kettle,for a hole will soon result from such an accident. 47 brittle than before, and the nap soon breaks off roundthe square.

Blocking. Previous to dyeing, all hats must be blocked, usingsuch blocks as approach the intended shape of the hat,and as soon as possible after the making departmentis concluded.

In the act of blocking, the conical form of the hatis lost for the first time. The hat is now immersed inthe hotting water of the kettle, and while wet and hotthe tip is stretched wide, and the whole thing simplydrawn down over the block, a tight cord is run downto where the band is to be and the brim flattenedout.
