that had molasses and bone charcoal, I gave molasses alone. 

 The other one, that had had nothing but the ordinary feed, I 

 began to feed with molasses. I kept this up from October 

 26th to November 20th. During that time, the cow that had 

 molasses and bone charcoal, now being fed on molasses, had 

 fallen off four pounds. The one fed with molasses and bone 

 charcoal, formerly fed with molasses alone, fell off three 

 pounds. The one having nothing but the ordinary feed at 

 first, but now having molasses, gained a pound. At that 

 time, November 20th, I ran out of molasses and was out four 

 days, and the cow that was giving then, on molasses, nine- 

 teen pounds of milk a clay, fell off to eighteen. The other, 

 that was giving thirty-three pounds, fell off to thirty. The 

 other, that was giving thirty pounds, fell off to twenty-seven. 

 My entire stock of molasses having gone, I thought I would 

 try a new experiment. There is about three per cent, of oil 

 in Indian meal, and I attributed the milk-giving qualities of 

 that meal to the oil there was in it, and I thought if I could 

 get my cows to eat an oil that comes from the coast of Africa, 

 called palm-oil, it would have the same effect. This oil is 

 made from a nut, and the natives use it as we do butter here, 

 but when it gets to this country, it becomes rancid, and is not 

 so pleasant. I thought if I could mix that palm-oil with mo- 

 lasses and make a kind of sauce of it, they might eat it. I 

 accordingly made a mixture of a pint of molasses, two ounces 

 of bone charcoal, and half a pound of palm-oil, gave it to one 

 cow daily, and she gained five pounds of milk a day, from No- 

 vember 24th to November 29th. Showing that, by combining 

 all the elements which are necessary to the food of a cow, the 

 phosphate, the oil and the sugar, that cow gained five pounds 

 of milk a day. I asked my man who did the milking, and also 

 my girls who took care of the milk, if they could see any dif- 

 ference in the quality of that milk, and they said the effect 

 was plainly to l^e seen in the color of tlie cream and in the 

 quantity. My cows were always healthy cows, and they 

 were giving very rich milk, but at this season of the year, 

 of course, they do not give milk so highly colored as at other 

 times. 



I have been experimenting in regard to coloring milk. I 

 have been giving what is called ground turmeric. This is
