the 8th February. The Scheduled District has now been extended so as to 

 include the remainder of the County of Southampton, and this brings the 

 Portsmouth district also within the Muzzling Area. An Inner Controlled Area 

 has also been prescribed round Southampton in view of the number of cases 

 confirmed in and near that town. 



Glamorgan . — There has been no development in this district. 



Berk-shire. — On the 13th January last, a case of Rabies was confirmed in 

 Basingstoke, which was within the existing Scheduled District, and also at 

 High Wycombe, just outside the north-eastern boundary of that district. The 

 former case did not involve an extension of the Berkshire scheduled district, 

 but the latter rendered ft necessary to add to the scheduled district an area 

 lying within a radius of about fifteen miles of High Wycombe. A second 

 case occurred at High Wycombe on the 22nd January, and one at Reading, in 

 the inner area on the 4th February. The inner controlled area was reduced as 

 from the 8th February to its original limits of 5 miles radius from Reading 

 which were fixed on 30th September last . 



London. — There have been no developments in the Metropolitan district, 

 and all restrictions have been removed except from the inner controlled area 

 (Acton district) and from a small portion of the borough of Woolwich, in 

 respect of which restrictions on M movement out n have been maintained as a 

 precautionary measure, owing to the report of a suspected case of rabies in 

 that borough. This case necessitates inoculation experiments being made 

 before a decision can be given. In the event of the decision being negative 

 the restrictions in res[>ect of this small area in Woolwich will be removed. 



Trench System of Ensilage.— In the Article on -Pit, Trench and 

 other Silos," by Mr. A. W.Oldershaw. which appeared in the February Journal, 

 a statement is made that u It is not suggested that the method of making 

 silage in pits or trenches results in material of the same high quality as that 

 made in cylindrical tower silos, bnt there is no doubt that thoroughly good 

 silage can easily be made in this way." 



The writer of the Article wishes to state that he has since had an 

 opportunity of making further investigations as to the quality of silage made 

 according to Mr. Makens* Trench System. Some excellent samples of silage 

 have been made this year by the above method, and Mr. Oldersliaw is now 

 quite convinced that if care is taken to make the silage exactly as described, 

 keeping it well trampled down and afterwards carefully covered up with 

 earth, the quality of trench silage is in no way inferior to the best 

 samples made in cylindrical tower silos. Moreover, if the silage in the trench 

 or pit is carefully topped up with useless material, jcc, it would appear that 

 the amount of waste on the top need not be materially greater than that 

 which often occurs on the top of cylindrical silos. Two trench silos were 

 constructed by Mr. Arthur Symonds, Shetland, Suffolk, during the past 

 year — in both cases on quite heavy land. Drains were arranged to drain off 

 the water, and it was found that there was no excessive amount of loss in 

 the trench. It is worthy of note that, with a cylindrical tower silo, if the 

 material is put in carelessly and without a sufficient amount of trampling round 

 the outside, quite a considerable loss may take place owing to air gaining 

 admission through the carelessness of those engaged in filling the silo.
