Hoven in Cattle : A Greatly Improved Stomach-tube. 



Cattle-farineis, })articulaily those liaving' jjedij^jiee st(i( k, will be 

 interested in an article published in this issue oi the JouriKil on the 

 subject of Acute Tympanites, or Hoven, in cattle. It is written by 

 Dr. Yiljoen, of the Division of Yet(Minary Education and Eeseandi, 

 and describes the ailment (which is defined as an abnormal accumula- 

 tion t)f gases in the larg'e stomac h), iiie causes, symptoms, and treat- 

 ment beiufj- clearly explained. There are both preventive and curative 

 treatments, and it is in re.spect of the latter that Dr. Viljoen draws 

 attention to a greatly improved stomach-tube that has recently been 

 ])roduced by Dr. Nuescli, of Switzerland. The instrument itself is 

 described and how it is used, and it is advised that it should 

 I (' l<c])t on the farm, for it may l)e found of considerable value 

 and be the means of saving the lives of animals. Cases 

 of acute tympanites usually dcvelo}) very ■suddenly, and, 

 unless immediate relief is aiforded, sufff)cation sets in, and death 

 generally takes place in two or three houis, sometimes soonei-. Where 

 the stomach-tube is not available the rumen (the first stomach) must 

 be punctured to permit the accumulated gas to escape; it is an opera- 

 tion accompanied by danaer. iunvever, and it is advisable that every 

 sto( k-owner should be provided with the jjrojjcr instrument. Further 

 particulars regarding Dr. Xuesch's invention and where it is ()])ta in- 

 able may be had on application to the Director of Veterinary Educa- 

 tion and Kesear(di, (Jnderstepoort, Transvaal.* 



The Control of Red Scale in Pears. 



Designed for tlie jjurpose of making it ]iossibie toi' the fruit- 

 grower to lessen considerably the cost of producing a cro]) of fiist-class 

 pears, spray experiments for the control of red scale in pear oichards 

 have been carried out at Elsenburg by Dr. Pettey, and are still in 

 l)rogress, and the results up to the present are given in an arti(de 

 "published in this issue of the Inujiuil. In recent numbers of the 

 Jounial valuable advice on a subject of mu(d) concern to fruit-growers 

 has been contributed liy Dr. Pettey, and the present article (a con- 

 siderable poition of which has already been published by the Western 

 Province Agricultuial Society in its journal) gives added information 

 that will further assist them in contending with orchard pests such 

 as red scale, f usicladium, and codling-moth, as well as the fungous 

 diseases. The rigorous control of the insect pests and fungous diseases 

 that invade the orchard is oik- of the most difficult and the most 

 important phases i;i the i;.nii e.oiioniy of the fruit-grower, and the 

 iuAestigations being cairied on by Dr. Pettey, and also by Mr. Put- 

 teiill, of the Division of J!otany, are of i)articular value to an industry 

 that Inis already established a lepulation on the oversea fruit-market 

 which, laises high the name of South African ])roduce. In the form 

 ])r]ncii)ally of articles and notes in tlie -hniriuil these two officers have 

 contiibuted v;ilual)b" additions lo the lilciature on a subject that every 

 fruit-<;i()wer, wln-ther toi Ilic local or oversea market, would do well 

 to study, for his success th j.ends hugely ujion the proper spraying of 

 (lis trees and at the right time.
