Poultry-house construction. (Storrs [Conn.] 81.) This bul- 

 letin discusses the general principles of poultry-house construc- 

 tion, with special reference to securing ample supplies of light 

 and air without draughts ; and gives plans and specifications for 

 several types of houses found useful at the Station. Directions are 

 also given for making the Connecticut trap nest, apparently a 

 very simple and effective type, and of the Connecticut dry-mash 

 hopper. 



VETERINARY SCIENCE 



Intradermal testing for bovine tuberculosis. (Mont. 105.) By 

 this method only small quantities of tuberculin are required, the 

 injection is very simple, and no thermal record is required, as 

 the index to the presence of tuberculosis is a distinct swelling 

 about the point of injection, usually in the smooth skin under- 

 neath the tail near its base. Some experience is necessary in in- 

 terpreting results, but this is easily acquired, and the indications 

 from the test are fully as reliable as from the ordinary injection 

 test. The reaction reaches its maximum from the twenty-fourth to 

 thirtieth hour, but the swelling remains for at least 70 hours, thus 

 making the test very convenient for inspectors. At least three times 

 as many animals can be tested by it as by the usual method. It 

 produces no interruption of milk flow. and interferes in no way 

 with herd routine. 



Hog-cholera "cures'' and specifics. (Iowa Circ. 25.) Seven 

 so-called hog-cholera cures or specifics were tested on 34 hogs, all 

 of which died after exposure to infection, as did six untreated 

 animals. Of six hogs treated with the Niles-Dorsett serum (ap- 

 proved by the U. S. Government and many Stations), not one 

 died. Warn all swine owners to beware of any proprietary hog- 

 cholera remedy ! 



FRUIT GROWING 



Fertilization of peach orchards. (W. Va. 150.) Four years' 

 work with fertilizers in peach orchards led to the following results : 

 On shale loam soil low in fertility, with Carman and Waddell 

 peaches, the yearly growth of trees treated with nitrate of soda 

 has been double that on no-nitrogen plats, the bearing surface at 

 the end of the second year being 21/2 times that on trees not given
