I send you a photograph of a petri- 

 fied stump in the so-called petrified 



"Heat" by Pepper and Mustard. 



Cambridge, Massachusetts. 

 To the Editor : 



Through what physical process is the sen- 

 sation nf heat produced in the mucous mem- 

 brane by pepper ami mustard? 

 Sincerely yours, 



Arthur A. Carey. 



White blood cells are rushed to the 

 spot for the purpose of protecting tis- 

 sues against an irritant. When the 

 white blood cells are at work energy is 

 actually liberated in the form of heat, 

 irritation of the tissues by pepper and 

 mustard excites activity in various se- 

 creting glands belonging to the diges- 

 tive apparatus, with a corresponding 

 liberation of heat energy. Pepper and 

 mustard upon the skin act more 

 slowly than upon the mucous mera- 

 1 ranes, but will produce an area of ele- 

 vated temperature, wherever they have 

 keen applied upon the skin with that 

 object in view — instance, the mustard 

 plaster. — Dr. Robert T. Morris. 



THE PETRIFIED STUMP. 



forest situated in Teller County, Colo- 

 rado, fifteen miles northwest of Crip- 

 ple Creek. 



There are several smaller stumps in 

 the immediate vicinity of this one, but 

 this is the largest in the forest, being 

 about ten feet in diameter. Many in- 

 teresting fossils are occasionally dis- 

 covered near the stump. 



Yours very truly, 



Mrs. Maud E. Welsh. 



All highways lead to nature, 



North, South and East and West ; 



And when you reach her portals. 

 She'll offer you her best.

Fido's Dream Comes True. 



BY HARRY BEELER, PHILADELPHIA, PENN- 

 SYLVANIA. 



I send you a photographic study of 

 a dog asleep, and apparently dreaming 

 of what is actually taking place in 

 front of his kennel. A turtle, a parrot 

 and a crow are stealing- his food. 



WHAT FIDO IS DREAMING.
