Modern Dog- Catchers Use Motor 

 Trucks and Wire Nets 



KEEPING apace with the times, 

 even the modern dog-catcher 

 now uses mo tor- trucks to collect stra\' 

 animals and haul them quickly to the 

 pound. One of the latest types of 

 dog-catcher's trucks is shown in the 

 accompanying illustration. It is 

 used in one of the western cities and 

 is equipped with an all-metal body 

 for cleanliness. It is divided into 

 eight compartments into which are slid 

 sixteen metal cages to confine the dogs. 

 The cages are pushed into place from 

 both sides of the truck, meeting at the 

 center. Four of the cages are sub- 

 divided into two parts each by horizontal 

 partitions. These are used for the small- 

 er animals while the remainder are 

 employed for large dogs. 



Each of the compartments has a 

 shutter-door which protects the animals 

 from the hot sun in the summer or snow 

 in the winter and which gives them 

 sufficient ventilation. 



Motor-trucks have proven particu- 

 larly adaptable for the dog-catcher 

 because of the large growth of suburban 

 territory about many of the big cities. 

 This has necessitated longer hauls than 

 horses could accomplish day in and da\- 

 out through all kinds of weather. 



Some dog-catchers prefer to use the 

 wire net in catching the animals. This 

 method is said to be far safer and surer 

 than other methods in vogue, such as 

 the wire noose and rope, both of which 

 are more or less cruel. The catcher using 



the net merely throws it over the dog; 

 the animal becomes entangled and is 

 then placed in the wagon without 

 further trouble. 



The Cockroach Attracts Attention 

 as a Trouble Maker 



RECENTLY while inspecting a large 

 plant attention was called to a 

 peculiar incident. On a branch circuit 

 there was some peculiar trouble. Fuses 

 would blow out at various intervals 

 running from one-half hour to twenty- 

 four hours. 



At first no attention was paid, but 

 when the ground detector started to 

 show signs of trouble, first on one side 

 antl then the other, an in\estigation was 

 made. t"o\-crs were removed from the 

 outlet boxes and from one box a shower 

 of live and dead cockroaches fell on the 

 head oi the examiner. On looking into 

 the box, it was found that the insulation 

 around the joints and especially at the 

 points had been entirely eaten away, 

 the vibration of the building doing the 

 rest toward creating the trouble.
