New Method of Protecting Property 



from Lightning. 



The Lightning Dispeller. 



Price, $20 to S30.— According to size. 



The Patent Lightning Dispeller is a conduc- 

 tor specially designed to dissipate the energy 

 of a lightning discharge, — to prevent its 

 doing harm, — placing something in its path 

 upon which its capacity for causing damage 

 may be expended. 



No recorded case of lightning stroke has 

 yet been cited against the principle of the 

 Dispeller. So far as known, the dissipation 

 of a conductor has invariably protected under 

 the conditions employed.

Sportsmen and ornithologists wil jOe interested in 

 the list of Labrador birds by Mr. L. W. Turner, 

 which has been kindly revised and brought down to 

 date by Dr. J. A. Allen. Dr. S. H. Soudder has con- 

 tributed the list of butterflies, and Prof. John 

 Macoun, of Ottawa, Canada, has prepared the list of 

 Labrador plants. 



Much pains has been taken to render the bibliog- 

 raphy complete, and the author is indebted to Dr. 

 Franz Boas and others for several titles and impor- 

 tant suggestions; and it is hoped that this feature of 

 the book will recommend it to collectors of Ameri- 



It is hoped that the volume will serve as a guide 

 to the Labrador coast for the use of travellers, 

 yachtsmen, sportsmen, artists, and naturalists, as 

 well as those interested in geographical and histori- 

 cal studies.

A MINIATURE STEAM-ENGINE. 



By the kindness of our correspondent, Mr. Max 

 Kohl of Chemnitz, Germany, we are enabled to 

 present to our readers an illustration of a miniature 

 steam-engine, recently constructed in his establish- 

 ment. Although so small as to fit easily within its 

 case, composed of an ordinary walnut shell, the 

 little machine is a practical working model, correct- 

 ly and completely finished in all its parts. The 

 cylinder, which is supplied with a complete sliding 

 valve, is 5.5 mme. in length and has a bore of 2 mme. 

 The boiler is 20 mme. in length and 8.5 mme. in 

 diameter. The diameter of the fly-wheel is 10 mme. 

 and that of the steam channels 0.2 mme. The slide 

 is 1.8 mme. in length and 1.7 mme. in breadth. The 

 machine is furnished with safety-valve, waste-cock 

 and funnel. The model is to be driven with a spirit 

 lamp, but it can also be put in motion by means of 

 a thin rubber tube, the one end of which is to be 

 screwed in the funnel on the kettle, while the other 

 end is supplied with a mouth f . r blowing air into 

 the kettle. The model only serves to show in what 

 small dimensions working steam-engines can be 

 made.

"This is a sprightly narrative of personal inci- 

 dent. The book will be a pleasant reminder to 

 many of rough experiences on a frontier which is 

 rapidly receding."— Sosfoii Transcript. 



" The picture of our desolate North-western terri- 

 tory twenty-five years ago, in contrast with its 

 civilized aspect to-day, and the pleasant features of 

 the writer's style, constitute the claims of his little 

 book to present attention." — The Dial.
