This is what might have been expected;--but those who have never considered with attention the extreme slowness of the progress of national improvements, WHERE NOBODY TAKES PAINS TO ACCELERATE THEM, will doubtless be surprised when they are told that in most parts of England, though the use of potatoes all over the country has for so many years been general, yet, to this hour, few, comparatively, who eat them, know how to dress them properly.-- The inhabitants of those countries which lie on the sea-coast opposite to Ireland have adopted the Irish method of boiling potatoes; but it is more than probable that a century at least would have been required for those improvements to have made their way through the island, had not the present alarms on account of a scarcity of grain roused the public, and fixed their attention upon a subject too long neglected in this enlightened country. The introduction of improvements tending to increase the comforts and innocent enjoyments of that numerous and useful class of mankind who earn their bread by the sweat of their brow, is an object not more interesting to a benevolent mind than it is important in the eyes of an enlightened statesman. There are, without doubt, GREAT MEN who will smile at seeing these observations connected with a subject so humble and obscure as the boiling of potatoes, but GOOD MEN will feel that the subject is not unworthy of their attention. The following directions for boiling potatoes, which I have copied from a late Report of the Board of Agriculture, I can recommend from my own experience: On the boiling of Potatoes so as to be eat as Bread.
