The street carts of the sanitary service now 

 in use in Paris are hauled by teams of dogs 



The Horses Have Gone to the Front, 

 So Paris Drives Dogs 



NOT only are large numbers of dogs in 

 training for Red Cross rescue work 

 on the battlefields, but in the industrial 

 world also, dogs are being utilized, espe- 

 cially in Paris. There the city officials 

 have assigned to the dogs the work of 

 the horses of the street cleaning and 

 sanitary departments. They are 

 driven in teams, and draw small 

 carts, somewhat larger than 

 dinary handcarts. 



Into these carts the 

 collected refuse is 

 placed in covered cans, 

 and an oilcloth cover- 

 ing is fitted over cans 

 and cart. The whiffle- 

 tree is attached to the 

 cart in such a manner 

 that the dogs may lie 

 down to rest without 

 inconvenience while the 

 carts are being loaded 

 or unloaded. 



The dogs make their 

 rounds in as good time 

 as the horses did for- 

 merly. The carts are 

 smaller than the old 

 horse carts; but there 

 are more of them. 

 The upkeep of the dog- 

 teams is considerably 

 less expensive tlvan 

 that of the horses. 



We Are Now Getting Natural Indigo 

 From Michigan 



ADVICES from Midland, Michigan, 

 A tell us of the first production of 

 indigo from coal tar in the United States. 

 One thousand pounds of 20% paste are 

 produced daily despite the fact that in 

 the last tariff bill the duty on dyestuffs was 

 removed from indigo. The annual con- 

 sumption of indigo in normal times is in 

 the neighborhood of 10,000,000 pounds. 

 By 191 2, the German makers of the coal 

 tar indigo, which is chemically the same as 

 the product of the tropical indigo plants, 

 had driven the natural product from the 

 world's markets. The artificial is consid- 

 ered better and more reliable than the 

 natural dye. — Ellwood Hendrick. 



The combination tie-rack, collar-but- 

 ton-holder and pincushion which hangs 

 on the wall beside the chiffonier 



Where's That Collar Button?— Why, in 

 the Button Rack, of Course 



NO longer need the bachelor fume and 

 the benedict distress the ears of his 

 household over a lost collar button. If he 

 is a really up-to-the-minute specimen of 

 American manhood he will simply reach 

 up to a convenient slab hanging on the 

 wall beside his chiffonier and get an- 

 other button out of the button-rack 

 which the slab carries. 



This little temper-saver is a com- 

 bination tie-rack, button- 

 holder and pincushion. 

 Its construction is sim- 

 plicity exemplified. A 

 central slab of wood has 

 a buttonhole groove at- 

 tached to it into which 

 six or more collar buttons 

 slide and are held ready 

 for use. * At the bottom 

 of the wooden slab a 

 pincushion is glued on 

 securely. Into this, stick- 

 pins may be thrust. Fin- 

 ally, at the sides of the 

 center slab are arms up- 

 on which an assortment 

 of ties may be kept in 

 plain view so that a 

 choice may be made 

 readily. - 



The device might rea- 

 sonably be called the 

 silent and ever-ready 

 valet.
