“Given at the council chamber in Dublin.” This is the first time we have been informed, by authority, that potatoes are a species of grain; but we must accede to this new botanical arrangement, when published under such splendid auspices. The assertion certainly is not made in distinct terms: but all who understand the construction of language must imply the conclusion that we draw from these premises. A general position is in the first member of the sentence laid down, “_that the greatest economy is necessary in the consumption of all species of grain_.” A particular exemplification of the principle is made in the next clause, “_especially in the consumption of potatoes_.” The inference is as plain as can be made. The next article in our newspaper is an advertisement of lands to be let to _an improving tenant_:--“A few miles from Cork, in _a most sporting country_, bounded by an _uncommon fine_ turf bog, on the verge of which there are a number of fine _lime kilns_, where _that manure_ may be had on very moderate terms, the distance for carriage not being many hundred yards. The whole lands being now in great heart, and completely laid down, entirely surrounded, and divided by _impenetrable furze ditches, made of quarried stones laid edgeways_.” It will be a matter of difficulty to the untravelled English reader to comprehend how furze ditches can be made of quarried stones laid edgeways, or any way; and we fear that we should only puzzle his intellects still more if we should attempt to explain to him the mysteries of Irish ditching in the technical terms of the country. With the face of a ditch he may be acquainted, but to _the back_ and _gripe_, and bottom of the gripe, and top of the back of a ditch, we fear he is still to be introduced.
