He has not only originated these improvements, or been the first to give them practical experiment, but he has laid down certain principles which will doubtless exercise much influence in shaping the industrial economy of agriculture hereafter in different countries.  One of the best of these principles he puts in the form of a mathematical proposition.  Thus:—­As the meat is to the manure, so is the crop to the land.  Tell me, he says, how much meat you make, and I will tell you how much corn you make, to the acre.  Meat, then, is the starting point with him; the basis of his annual production, to which he looks for a satisfactory decision of his balance-sheet.  To show the value he attaches to this element, the fact will suffice that he usually keeps 65 bullocks, cows, and calves, 100 sheep, and a number of pigs, besides his horses, making one head to every acre of his farm.  With this amount of live stock he makes from 4 to 5 pounds worth of meat per acre annually.  Perhaps it would be safe to say that no other 170 acres of land in the world make more meat, manure, and grain in the year than the Tiptree Farm.  In these results Mr. Mechi thinks his experiments and improvements have proved

Having gone over the farm pretty thoroughly, and noticed all the leading features of the establishment, I was requested by the foreman to enter my name in the visitor’s book kept in his neat cottage parlor.  It is a large volume, with the ruling running across both the wide pages; the left apportioned to name, town, country, and profession; the right to remarks of the visitor.  It is truly a remarkable book of interesting autographs and observations, which the philologist as well as agriculturist might pore over with lively satisfaction.  It not only contains the names and comments of many of the most distinguished personages in Great Britain, but those of all other countries of Europe, even of Asia and Africa, as well as America.  Foreign ambassadors, Continental savans, men of fame in the literary, scientific, and political world have here recorded their names and impressions in the most unique succession and blending.  Here, under one date, is a party of Italian gentlemen, leaving their autographs and their observations in the softest syllables of their language.  Then several German connoisseurs follow in their peculiar script, with comments worded heavily with hard-mouthed consonants.  Then comes, perhaps, a single Russian nobleman, who expresses his profound satisfaction in the politest French.  Next succeed three or four Spanish Dons, with a long fence of names attached to each, who give their views of the establishment in the grave, sonorous words of their language.  Here, now, an American puts in his autograph, with his sharp, curt notion of the matter, as “first-rate.”  Very likely a turbaned Mufti or Singh of the Oriental world follows the New England farmer.  Danish and Swedish
