To four pounds of bread : two table-spoonfuls of the above 

 yeast, made into a sponge ; then put the bread to rise, mixed 

 with milk, and let it stand with a tea-spoonful of water knead- 

 ed into the dough. Then put it into the bake pans, and stand 

 in a warm place fifteen or twenty minutes. 



Agricultural Implements. 



The two important implements herein named, were exhib- 

 ited at the late fair of the society, but were not entered for 

 premium. 



The self-adjusting ox yoke, patented November 20th, 1849, 

 by John Chase, of Craftsbury, Vermont, is constructed of one 

 piece of straight plank, having a plate of iron on each edge riv- 

 eted on to the plank by rivets passing through the width of the 

 wood and thickness of the plates. The plank can be increased 

 in width and thickness, as well as the iron plates, to give it all 

 the strength that the most severe test can require of an ox yoke. 

 It is constructed with sliding neck pieces, made secure to the 

 top piece of plank or main beam, by bands of iron passing round 

 the beam or plank ; and so constructed by a simple rack made 

 fast to each neck piece, and connected by a pinion, so as to ex- 

 pand or contract with great ease, to make a long or short yoke 

 at will. This rack can be so arranged as to give an advantage 

 to the weakest ox to an extent of six inches. The bunk, or 

 staple-piece, under the beam can, when the yoke is made, be 

 made to draw high or low, as desired. The bunk is fastened 

 to the beam by a strap of iron, in the usual way, which makes 

 the whole strong and simple. 



The merit of this yoke over the common one, is its great 

 strength ; the ease with which a weak ox can have an advan- 

 tage to the extent of six inches ; the sure preventive of the 

 awkward posture of crowding or hauling: the ease in which 

 they work in the neck pieces, — and thus, freedom from sore 

 necks. Some objections may yet be found to this yoke, but 

 the subscriber has had one in use nearly three months, and 

 from his experience he can freely recommend this yoke as su- 

 perior in every respect to the old one, and quite as cheap.
