In the old barn the average pounds of milk per head per week was, for seven weeks, respectively: 95.9, 80.4, 

 85.3. 80.1, 94.5, 89.8 — an average weekly yield of 87.96 pounds. 



The cows were then installed in the remodeled barn and the average pounds of milk per head rose as follows: 

 First week 84.8 pounds, then four weeks following respectively 106.7. 116.7. 116.1. 108.5. an average for the five 

 weeks of 106.56 pounds, or an average for the final four weeks of 1 12 pounds. 



Comparing the average of the last four weeks, with the average of the seven weeks in the old barn, shows an 

 increase of 3.43 pounds per cow, per day. 



Mr. Mathei also states that the cows were fed in both barns the same rations of seven pounds of grain food 

 per pound of butterfat and 30 pounds of silage, with 10 pounds of hay per 1,003 pounds of live weight. 



The equipment m the new barn which he mentions, is "James." 



ONE TO TWO POUNDS INCREASE — ONE HOUR LESS WORK 



Chas. Hoffman, Denmark, Wis., December 20. 1917, writes: "I have no records to show the increase of milk 

 yield after starting to use water buckets. But my estimate is from one to two pounds a day from each cow. 



"I know through experience that a cow watered in the barn during the day and again at night will give more 

 milk than one watered outside only. 



"The water buckets save me at least one hour a day. My cattle were watered from a tank outside and didn't 

 use a heater, and it was poor business, too. I am well satisfied with the buckets and will also tell you that the 

 cows drink just as much water during night as in the day time." 



ONE TO THREE POUNDS INCREASE 



N. J. Jacque, Port Washington, Wis., under date of December 26, 1917, writes: "When I put in water buckets 

 my milk increased per cow from one to three pounds a day. I was weighing the milk from every cow and gave the 

 same feed as before. 



"I save about every day one half to three quarters of an hour with the water bucket. Before I had the water 

 buckets they got their water at the tank in the yard and was fresh pumped from the well." 



MILK INCREASE PAYS FOR CUPS IN THREE MONTHS' TIME 



A. F. Dale, Lockport, N. Y., December 19, 1917, writes: "My milk yield increased after starting to use James 

 drinking cups due in my opinion to their use, enough to pay for them in three months' time. Also, they save me 

 one and a half hours a day. 1 used to water from a tank in the yard, but did not warm the water." 



INCREASE 20 POUNDS WEEK PER COW 



Harry K. Jarvis. Weedsport, N. Y., December 24, 1917. writes: "I find that since putting in the James drink- 

 ing cups due in my opinion to their use, my cows have increased about 20 pounds per week per cow. These figures 

 are an estimate but are accurate, as the increase is shown by more cans of milk. " 



James Watering System is Simple 



The James watering system is simple, requiring for the gravity system only the cups; 

 the control tank with regulating valve to maintam a uniform level of water in the cups ; 

 a source (such as a supply tank or spring on a level higher than the regulatmg tank) from 

 which the regulating tank may draw the water ; and the necessary piping to connect the 

 same. It is easily installed, and once in requires practically no attention — and the cows 

 have pure, fresh water before them every moment of the day and night. 



The level of the water in the cups is regulated by the level of the water in the regulating 

 tank, these levels, of course, being the same. The level of the water in the regulating 

 tank is maintained by a float valve; this regulating tank taking its water from any source 

 having a sufficiently high level to feed regularly. 



With the pressure system no regulating tank is required. 



The James Drinking Cups 



There are four styles of James drinking cups, a one-cow cup and a two-cow cup for 

 the gravity system and a one-cow cup and a two-cow cup for the pressure system. 



One of the best features of these cups is that they are so simple in construction and 

 operation as to be practically trouble proof. They are so easy to install that any dairyman 

 can equip his barn quickly and easily. And being automatic in action, very little further 

 care or attention need be given them once they are in place.
