Prof. Mapes. The sugar refiners use sometimes milk, instead of 

 blood in their process — there being a prejudice against the use of blood. 

 For that purpose the cream must be entirely separated from the milk. 

 The following method is adopted for that purpose. Pans containing 

 some five gallons of milk are used, having rims by -which they are 

 readily handled; on the bottoms of these pans, strips of zinc are laid 

 with their ends bending over the sides and touching the shelves on 

 which the pans rest — and this in a cool damp situation. The effect 

 of this practice is, that the cream rises much more rapidly to the sur- 

 face of the milk, is much more perfectly separated from it, and then 

 the milk is drawn off below through holes in the bottoms of the 

 pans. 



Col. Edward Clark remarked that pans of zinc coated with tin 

 had been employed for this purpose, and it was found that galvanic 

 action produced a rapid rising of the cream. 



Ambrose Stevens. A gentleman at Vernon, originally from De- 

 vonshire, had used zinc pans in his dairy, to facilitate the rising of 

 cream. He showed me the difference between the effect in tin, and 

 in zinc pans. The same milk gave its cream several hours later in 

 the tin than in the zinc pans. 



Mr. Wakeman remarked in reference to the petition for our Ag- 

 ricultural School, &c., that it had been said, all the petitioners were 

 in this city only, but he knew perfectly well, that out of any 500 

 citizens to whom he might apply for their signature to the memori- 

 als, not one would refuse! But had we time Jo ask every man? 

 The importance of such a school, such a system of education, and 

 that too, to be commenced near this great city, where every possible 

 advantage existed to insure its success, was too apparent for argu- 

 ment. But we mean to buy the land, and then the Legislature see- 

 ing that we are seriously in earnest, will without a doubt, aid us in 

 the foundation of this new and admirable system of Agricultural Ed- 

 ucation. 



Judge Van Wyck. We Americans are fully equal to our Euro- 

 pean friends in our stock of cows, which give as much milk and of 

 as fine quality as any they have. But we do not equal them in the 

 quality of the cheese and butter for exportation. We make as good 

 for our domestic consumption however, generally speaking; we like 

 to eat the best butter, and we do it. Those who make the best have 

 as much custom as they want, they are sought after. But we export
