90 TRANSACTIONS OF THE AMERICAN INSTITUTE. 



" I have liad in oppriition two liorse and tliroo ox niacliines. One 

 inacliiiic was worked 33 days, witli tlii' Ranif team of four luiiscs. At tlie 

 end of the season their condition sliowed tliat tlio work had not been harder 

 for them than ordinary ph)win<if. The ox rnaeliines require a team of two 

 or tliree jniirs of oxen each. A portion of the season I worked two of tlic 

 ox machines g-anp^ed with six jiairs of oxen, one man manajj^in^ tlie team 

 and spaihrs readily. Four of tiie spaders are three ieet in width each. 

 For a It \v days in the hitter ]>art of tlie season I had at work one three 

 feet eight inches wide, which is the usual widlii of our corn rows. IL is 

 proposed to construct the most of them hereafter this width, and attach a 

 sell-actinn" corn-planter. This will be capable of »spading' and plantinj^one 

 acre [)er hour, Mith a speed two and a quarter miles, al a cost not exceed- 

 ing' 44 cents |)er acre, allowing eight iiours as a day's work. As a labor- 

 saving imidement, and a deep and thorough tiller ol" tlu^ soil, I am greatly 

 jileased with it, and shall watch with a good deal of interest the product 

 of the crop at maturity. At present there is no perceptible difl'erence in the 

 appearance of the corn on the plowed and spaded land, but J .shall expect 

 a yield of Irom 10 to 25 per cent in favor of the latter." 



The Chairman — The Club will be very glad to have the result c»f the 

 yield. If the dmulh has been as severe there as it has here tli<' yield of the 

 deep tilth will be double that of the shalh)W, and more than ten fold pay 

 the cost.

Agreeabh; to usage, on adjourning the Club lor the day it was agreed to

 recess to make a note of all such facts as he may thiid< will add interest to 

 our discussi(jns or be of value to the large number of persons who read the 

 rejioits of our proceedings. We hope our friends in the country who have 

 sent Mr. llobinson and the Secretary so iducIi valuable and interesting in- 

 ffjrmation will continue their good work. \\'e hope at the next meeting 

 they will have u budget of letters from tlie people wliich will furnish us 

 ample matter for discussion without lixing upon any regular (piestion for 

 debate. Atljourned. Jon.s \V. Chamhi i:s, Srcrrlarij.
