New Method of Protecting Property 

 from Lightning. 



The Lightning Dispeller. 



Price, $20 to $30.— 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. 



Correspondence solicited.

Sportsmen and ornithologists wil oe Interested in 

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

 which has been kindly re-vised and brought down to

 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 tor several titles and impor- 

 tant suggestions; and it is hoped that this feature of 

 the book will recommend it to collectors of Ameri- 

 cana. 



It is hoped that the volume will seive 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. Mas 

 Eohl 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 sinall as to fit easily within its 

 case, composed of an ordinary walnut shell, the 

 little machine is a practical working model, corrpct- 

 ly and completely finished in all its parts. The 

 cylinder, whicti 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 I'-ngth and 8.5 mme in 

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

 and that of the steam chanuels O.S mme The slide 

 's 1.8 mme. in length and 17 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.

 many of rough experiences on a frontier which is 

 rapidly receding."— .Bosfoji 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 bis little 

 book to present attention." — The Dial.
