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 o£ the 

 Dispeller. So far as known, the dissipation 

 of a conductor has invariably protected under 

 the conditions employed. 



Correspondence solicited.

Sportsmen and ornithologists wll oe 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. Scudder 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- 

 cana, 



It is hoped that the volume will serve as a guide 

 to the Labrador ooast for the use of travellers, 

 yachtsmen, sportsmen, artists, and naturalists, as 

 well as those interested in geographical and histori- 

 cal studies.

RACES AND PEOPLES. 



By DANIEL G. BRINTON, M.D. 



"The book is good, thoroughly good, and will long 

 remain the best accessible elementary ethnography 

 in our language." — The Christian Union. 



"We strongly recommend Dr. Brinton's 'Races 

 and Peoples' to both beginners and scholars. We 

 are not aware of any other recent work on the 

 science of which it treats in the English, language. *'■' 

 — Asiatic Quarterly. 



"His book is an excellent one, and we can heartily 

 recommend it as an introductory manual of ethnol- 

 ogy."— T/ie il/oms^. 



"A useful and really interesting work, which de- 

 serves to be widely read and studied both in Europe 

 and America." — Brighton (Eng.) Herald. 



"This volume is most stimulating. It is written 

 with great clearness, so that anybody can under- 

 stand, and while in some ways, perforce, superficial, 

 grasps very well the complete field of humanity."— 

 The Nexo York Times. 



"Dr. Brinton invests his scientific illustrations and 

 measurements with an indescribable charm of nar- 

 ration, so that 'Races and Peoples.** avowedly a rec- 

 ord of discovered facts, is in reality a strong stim- 

 ulant to the imagination. "—Philadelphia Fublic 

 Ledger. 



"The work is indispensable to the student who re- 

 quires an intelligent guide to a course- of ethno- 

 graphic reading." — Philadelphia Times.

Driving tlie Brain 



at the expense 

 of the Body. 

 While we drive 

 the brain we 

 must build up 

 the body. Ex- 

 ercise, pure air 

 — foods that 



make healthy flesh — refreshing- 

 sleep — such are methods. When 

 loss of flesh, Strength and nerve 

 become apparent your physician 

 will doubtless tell you that the 

 quickest builder of all three is 



ScGtt's Emulsion 



of Cod Liver Oil, which not only 

 creates flesh of and in itself, but 

 stimulates the appetite for other 

 foods.

" 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
