Experimental. 



Forty-nine maunds^ of seed costing Rs 5/-- per maiind were crushed 

 in ordinary wooden kolhus or country mills at Bahraich and the total 

 production of oil and cake was sent to us at Cawnpore. A certain 

 amount of oil leaked out of the receptacles on the journey, but 17 mds. 

 10 srs. of oil was received at Cawnpore. This was sold at Rs 18/- per 

 maund, there being a good demand for it. A bid of Rs 18/10/- per maund 

 was made after we had closed with the offer of Rs 18/-. The cost price 

 of the seed was thus Rs 245/- and crushing charges at Rs 1/4/- per 

 maund amounted to Rs 61/4/-, bringing the total cost to Rs 306/4/-. The 

 oil realised Rs 308/15/-. Thirty maunds of cake were received and the 

 value of this represents the profit on the transaction. Of course there 

 were charges for carriage amounting to about Rs 30/- but the seed 

 could equally as well have been purchased and crushed in Cawnpore. 



Oiu' experiments were designed to see if we could detect any noxious 

 property in poppy seed cake and not to test its actual food value. The 

 latter can only be done by extended trials such as the Danish feeding 

 trials involving the use of large herds of animals. For this we had 

 neither the animals nor the facilities. 



One cow (Phulia) and two buffaloes (Rukminia and Lachminia) 

 were chosen for the experiment. The animals were all in good condition. 

 The cow was of the country breed known as Kosi and the buffaloes 

 belonged to the Murrai breed. Phulia had had her eighth calf (date of 

 calving, 13th March, 1918). Rukminia and Lachminia had had their 

 fourth and third calves respectively (dates of calving, Rukminia, 28th 

 November, 1917, and Lachminia, 28th May, 1918). Rukminia was thus 

 at the end of her lactation period and dried off during the last week of 

 July. 



The buffaloes received a daily ration of 20 lb. straw, 6 lb. bran, 

 3 lb. chuni (the outer husks and broken pieces of the pulses) and 3 lb. 

 mustard cake. The cow's feed consisted of 13 lb. straw, 6 lb. bran, 

 2 lb. chuni and 2 lb. mustard cake. The animals were also allowed to 

 graze. From the 1st July the supply of the mustard cake was stopped 

 and an equal amount of poppy cake substituted instead. The feeding 

 of poppy cake was continued for a little over six weeks. On the 14th 

 August the poppy cake in the ration was replaced by mustard cake. 



The cattle were weighed in the beginning of June while still on a 



' 1 maund = 82-2 lb., 40 seer.s = l inaund. 

 2 1 rupee = 2s. Orf. (Oct. 1919).
