Advantage may be taken of the fact that bed-bugs oviposit in warm, 

 dry places. A simple method consists in putting sheets of corrugated 

 paper, such as is used for packing purposes, under matresses and among 

 bedclothes. Oviposition occurs in May and if the sheets be removed, 

 burnt, and replaced weekly during that month, a repetition of this 

 procedure during a number of consecutive years will free buildings from 

 this pest.

An anti-mosquito ordinance has been enacted by the city of Tyler, 

 Texas. No stagnant water may be maintained within the corporate 

 limits of the city unless constantly drained, or oiled, or screened, or 

 kept stocked with mosquito-destroying fish and free from vegetation. 

 No receptacles containing water in which mosquitos may breed are 

 allowed, unless subject to measures preventing breeding ; this also 

 applies to gutters, eaves, excavations, etc. All ordinances in conflict 

 with this one are repealed. Violation of the above provisions con- 

 stitutes a misdemeanour and is punishable by a fine of from 1 to 10 

 dollars. Every day's continuance of such violation shall be considered 

 a separate offence. 



Barber (L. B.) Report of the Animal Husbandman and Veterinarian. 



— Rept. Guam Agric. Expt. Sta., 1915, Washington, 1916, 

 pp. 23-41, 4 figs., 3 plates, 1 table. [Received 19th October 1916.] 



The tick infesting cattle, horses, buffalos, goats and deer in Guam is 

 indistinguishable from Marga.ropus caudatus. Cattle in particular are 

 infested throughout the year, the ticks being specially abundant during 

 the dry season. Native cattle, as a result of tick infestation and 

 continuous inbreeding, are weak and undersized. Imported animals 

 become rapidly infected and the resulting fever may cause death at anv 

 time, or the animal may continue to live in an emaciated condition. 

 The conditions prevailing in Guam render the eradication of ticks or 

 the enforcement of quarantine regulations extremely difficult. Hand- 

 picking of ticks and the application of oil and kerosene have proved 

 unsatisfactory. The native method, which has proved of some value, 

 is to stand the animal in sea-water for an hour or more, then to scrape 

 the skin to remove ticks and fi.nallv to rub in lemon iuice. The treat- 

 ment is repeated two or three times at intervals of from six to eight 

 days. Plans are being made for dipping cattle at regular intervals in 

 order to eradicate ticks. External parasites of poultry in Guam 

 include two species of lice, Menopon piallidum and Goniocotes gigas, 

 and the mite, Dermanyssus gallinae.
