943 Summary of Agricultural Experiments, [feb., 



Narcissus Fly (Jour. Roy. Hort. Soc, October, 191 1). — The Nar- 

 cissus Fly, Merodon equestris, Fab., was scheduled in 1910 by the 

 Board under the Destructive Insects and Pests Acts. It has generally 

 been supposed to confine its attacks to the bulbs of narcissus. Mr. 

 F, J. Chittenden, however, reports that in November, 1910, bulbs of 

 Atamasco Lilies (Habranthus pratensis), and Scarborough Lilies ( Val- 

 lota purpurea), were sent to the Wisley Laboratory containing grubs 

 which were later proved to be those of the Narcissus Fly. Cases of 

 the fly attacking the bulbs of Lilies and Barbados Lilies (Hippeastrum) 

 are also mentioned, and it is concluded that the Narcissus Fly will 

 attack and destroy the bulbs of other plants than the daffodil, and 

 any effort designed for its extermination should take this possibility 

 into consideration. 



Live Stock and Feeding Stuffs. 



Soy Bean Cake for Bullock Fattening (Edinburgh and E. of Scotland 

 Coll. of Agric, Rept. xxv.). — These experiments were a continuation 

 of those carried out by the college in 1909-10 with the object of com- 

 paring soy bean cake with linseed cake as a supplementary feeding 

 stuff in fattening bullocks. The other food given varied slightly ; at the 

 first centre it consisted of 100 lb. turnips, 8 lb. straw, and 4 lb. Bombay 

 cotton cake daily, and at the second, of 100 lb. swedes, 7 lb. oat straw, 

 2 lb. dried grains, and 3 lb. Bombay cotton cake. At the latter 8 lb. 

 of hay was substituted for the straw in the last month. In both cases 

 either linseed cake or soy bean cake was given at the rate of 2 lb. per 

 day at first, increasing to 5 lb. during the last seven weeks. In the two 

 years together 36 cattle were fed on each food, and the trials show 

 that soy bean cake used as a supplementary feeding-stuff to the extent 

 of 4 or 5 lb. per head daily, is a healthy cattle food, and a satisfactory 

 beef producer. Weight for weight it is not equal to linseed cake, but 

 when its lower price is taken into consideration, it has the advantage. 



Pig Feeding Experiments (West of Scotland Coll. of Agric, Bull. 

 No. 57). — During the years 1905-10 a series of seven experiments was 

 carried out at the Dairy School, Kilmarnock. The object was to 

 discover how best to utilise separated milk and whey in pig feeding, 

 and what meals or mixtures of meals might be profitably used to 

 replace or supplement the liquid food. 



Five experiments were conducted between 1905 and 1908 with lots 

 of young pigs. The number in each lot was eight in 1905 and four 

 or five in succeeding years. All the lots were kept under the same 

 general conditions. The pigs received practically an ad lib. quan- 

 tity of food, though careful record was kept of the quantities actually 

 consumed. The meals were not cooked or scalded, but were soaked for 

 about twelve hours in cold waTer. Except in one case, where the effect 

 of cold foods was tested, the food was given warm. In 1905 the foods 

 used were: — (1) Separated milk and barley meal; (2) whey and barley 

 meal ; (3) water, barley meal, and a little bran ; (4) whey and maize 

 meal ; (5) whey and Paisley meal (the latter a local by-product of maize, 

 rich in abuminoids and oil) ; (6) whey alone. These w T ere repeated 

 in two experiments in 1906, with the addition of whey and Paisley 

 meal fed cold. In 1907-8, in addition, one lot was fed on whey and 

 barley meal during the first twenty-eight days of the feeding period,
