putting it, well spread out, on a shovel, or in an old tin or iron utensil 

 of any kind which can go on top of the fire and get red hot. How does 

 the burned soil compare with the unbumed in measure? In physical 

 condition? How do you account for the change? 



Expose the three soil samples to the air again for a day or two, to 

 equalize their moisture condition, for the " cooked " soil has become 

 excessively dry. If you can, take equal weights of the burned and the 

 unbumed humus soil, and the same weight of the mineral soil; or equal 

 measures, if you can not weigh. Weight is better than measure to give 

 you equal quantities of the three kinds of soil. Then put all three 

 samples in the lamp chimneys, as directed in the January Leaflet 

 (p. 109), and slowly pour on equal quantities of water. Which sample 

 has the greatest power to absorb water? How would they behave if a 

 heavy rain were falling? Would the rain most quickly run off the top 

 of the ground from a soil like the first, the second, or the third? 



What makes muddy brooks? What effect do forests have on the 

 purity of streams, and why? 



What is the result of repeated light fires on the moisture-holding 

 power and fertility of forest soil ? They do not, of course, have the effect 

 of the cooking in the experiment, but what do they bum up ? 



MILK RECORDS 

 W. A. Stocking 



EVERY dairyman should know as nearly as 

 possible how much milk and butter-fat he 

 receives from each cow in his herd. This is 

 the only way by which the dairyman can know 

 how much profit he is making on each cow. If 

 he does not know the yield of each cow, it is 

 more than probable that he is keeping some of 

 his cows without making any profit, and pos- 

 sibly at a considerable loss. The only way we 

 can know how much milk each cow is producing is to keep an accurate 

 record. This can be done either by weighing or measuring the milk 

 every day or for one or two days each month. If a record of the milk 

 for one or two days each month is taken, this will give a fairly correct 

 idea of what each cow will produce during the year. A chart like 

 No. I makes a very easy way to keep this sort of record. This 

 sheet can be made any desired size, sufficient to hold the records of 

 any number of cows which may be in the herd. If one wishes to keep
