jng the nvorage yield of milk in poiinds per cow per day for each 

 week, and the average per cent of solids and of fat for the last three 

 days of each week, together with averages of these data for three 

 periods of four Aveeks each, and one period of three weeks. Reference 

 is nuide to an experiment v\ith similar resnlts at the Kansas Station. 

 (See Annnal Report of Kansas Station for 1888, p. 69.) 



"■ The tables show that there Avas a steady and constant diminishing 

 in the flow of milk of both lots, bnt that lot 2 fell away in their milk 

 yield much more rapidlv than lot 1. At the same time, if we except 

 the last tAvo Aveeks (of Avhich mention Avill be made later), the milk of 

 lot 2 showed a constant raid considerable increase in percentage of 

 fats Avhile that of lot 1 remained very nearly stationary. For this 

 reason there Avas very little diflVreuce in the total amount of fat 

 prodnced by the tAAo lots." 



•• While Ave received no return in milk and butter for the extra 

 grain fed, Ave sliould scareeh' Avant to say that the grain Avas fed at a 

 loss, for tAA-o reasons: First, there must haA^e been a considerable 

 saving in pasture; in other Avords, Ave should haA^e been ahle to keep a 

 larger number of coavs in the same j^asture. Second, the manurial 

 A'-alue of the grain at pres^^nt prices of fodders and fertilizers, Avould 

 go far toward balancing its cost." Attention is called to the fact that 

 climatic conditions may haA-e influenced the results. The season Avas 

 unusually j-ainy, and it was obserA^ed that during the period of the 

 least rainfall and the highest temperature, when the conditions ap- 

 proached those of the ordinai'v season, the grain ration seemed to 

 have the greatest eft'ect. In the last tAvo Aveeks of the experiment, 

 when more or less rain fell on every day but one and the Aveather Avas 

 " raAv," the percentage of fat in the milk of lot 1 decreased 9 per cent. 

 Avhile that of lot 2 decreased 20 per cent. 



While the average analysis of the milk for three days was invaria- 

 bly above the retpiired legal standard, yet there Avas one day when the 

 milk for one lot fell below the legal requirements of 12 per cent total 

 solids. This suggests that it is liardlA' fair to impose a heaA^y fine or 

 imprisonment as the result of a single analysis of milk.

 vestigations of the life history of the finigus causing this disease, 

 made by the author. Avith the assistance of Miss J. W. Snow. Sug- 

 gestions as to remedies are also given, and the bulletin is illustrated 

 Avith cuts from original di'aAvings. The ncAV points brought out are 

 indicated in the following sunnnary. taken from the bulletin: 



1. Sijlitirella fni;/aria', Saccardo, passes the Avinter in this region in at least 

 three (lifforcnt conditions : (1) as mycelium in the leaves near the spots ; (2) in 

 the so-called sclerotia ; (.3) as ascospores in perithecia.
