Vigour in production-bred flocks, by F. A. Hays and R. Sanborn, Massachusetts Sta. Bul. 242, 1928, pp. 149–175, figs. 4.

The studies reported cover a 5-year period beginning with birds in the flock hatched in 1922 and ending with the flock hatched in 1926. The birds have all been pedigree-bred since 1913, and the greater proportion have been bred for high fecundity, with a limited number for other purposes (E.S.R., 59, p. 72). The chicks have been placed in brooder houses on clean range at 1 day old, and the sexes separated at 8 weeks. The pullets were put in the laying house at 150 days of age. All culling has been done by families only, and no pullets were culled at any time in the laying house.

Breeding as Affecting Egg Production.

The work under this project this year is a continuation of that carried on the previous year. The progeny of Cocks 113, 114, 115, and 116, were trapnested during the year. Cock No. 116 is the outstanding breeder, none of his pullets laying less than 100 eggs up to October 1, and 58 per cent of them laying over 180 eggs. Pullets hatched in the spring of 1927, are being trap-nested this year, but their records are not complete. Other pullets which were hatched in the spring of 1928 are being held and will be trap-nested the coming year. In addition to breeding White Leghorns for increased egg production, breeding work is being done using White Rocks and Barred Rocks in an endeavor to establish a White Rock high-egg producing strain.

B. pullorum in Turkeys, by Dalling, Mason and Gordon. The Veterinary Record, 12 Oct. 1929.

In 1928 the writers found Pull. Bacilli in sparrows. In 1891 Lucet explained the possibility of infecting turkeys. In 1928 Hewitt found B. pullorum in turkeys in the United States. Dalling found this also in the liver of a young turkey. Several chickens had died at the same farm. It is probable that the turkeys became infected through contact with the chickens.

The transmission of ultra-violet light through tracing cloth, by C. H. Young. Nature, London, 123, 1929, No. 3089, p. 47, fig. 1.

A brief communication announces that ordinary commercial tracing cloth transmits ultra-violet light to a surprising extent. The transmission is not affected to a marked degree by the thickness of the cloth and number of meshes to the centimeter. In angstrom units the limit of transmission was 2,535 for three samples of the cloth and 2,482 for two others, while the limit of various papers tested lay between 4,339 and 3,125.
