measured ; the Short-Horn was found to give mne and the Here- 

 ford six quarts at a meal. The milk was set up and churned se- 

 parately ; that from the Hereford produced nine pounds, and the 

 Short-Horn not quite Jive pounds of butter per week. They 

 stood in the same stall — were fed on the same description of food, 

 and had been kept alike previous to calving. It has also been 

 proved that two quarts of milk from a Hereford, will produce as 

 much curdzs three from a Short-Horn cow. The gentleman is now 

 crossing his Short-Horn cows with a Hereford bull, with a view 

 of improving the quality of his milk," 



POTATOES.— EXPERIMENTS. 



I 



During the coming season judicious experiments ought to hi 

 made with the potatoe, to ascertain, if possible, more of the disease 

 which has made such ravages in it for the last two years, and alsc 

 the best mode of curing or preventing it. And to do this, Ic) 

 every farmer bestow particular attention upon all the circumstance! 

 connected with planting and cultivating them, such as the follow 

 ing : — whether they are most affected in old tilled land, or tha" 

 which has been lying still in fallow or in grass for some years— 

 whether in manured land or that which has not been manured— 

 whether one kind of manure seems to be better for them thai 

 another — the effect of saline substances as nitrate of soda, saltpetre 

 lime, plaster, ashes — whether they succeed best in shaded land o: 

 that which is exposed to the sim— in di-y or moist land — and the 

 peculiarity of the soils in which they arc most and least diseased 



We can conceive that great practical good may result from sucl 

 observations, if generally and carefully made. The date upor 

 which the disease is first observed should be noticed — the tempe- 

 rature of the air for a few days about that time, and the tempera 

 ture of the earth, both on the surface, and about four inches be 

 neath it. Such observations are attended, it is true, with somt 

 extra trouble, but if they are followed up systematically, the trou 

 ble will not be thrown away. Let every thing be noted down ot
