MODEL OF A BARN, WITH A PLATE ANNEXED.

To the Editor of the Agricultural Magazine. SIR, E live at a time when persons affect to conzider that Y the principles of philosophy in general, and of ma- thematies in particular, are Successfully applied to the ordinary concerns of liſe. Notwithstanding this position is s0 fondly assumed by many of your intelligent correspondents, a little attention will discover that these principles are, in many cases, generally misunderstood, and in others wholly abandoned. Your last number contains Some account ot the agriculture of Norfolk, which I have read both with pleasure, and in- Struction.“ 1 have therefore been disposed to express my gra- titude by inclosing the annexed drawing of a barn, constructed by Mr. Henry Dobson, ot Norwich, the description of which was by him communicated to one of the best public institu- tions in this country.*; The following are the dimensions of a barn fifty feet long, - by twenty and a half wide.

Dimensions of the Model. Dimensions of the Common Barn. 1,475 Square feet the area. 1,475 Square feet the area. '30,900 pubic feet for. corn| 24,428 Cubic feet for corn only. only. 445 Cubic feet of timber. 702 Cubic feet of. timber.

By which calculation it appears that a barn, built on the present model, gains on one in common use of the Same area 6,472 cubic feet of space, and is built with 257 cubic feet of tmber less: as there is nothing in its construction which would increase the expence of workmanship, the difference between the expence of building a barn on this plan and that of one in common use, of the Same area, would be as 445 is io 702. Itis"npeedless to Say any thing of its mathematical “trength, and it must be obvious to any one who is at all ac- quainted. with mechanics, that the prezent figure is of all others the best calculated to answer that purpose.
