HOUSEHOLD ARTS AT THE WORLD'S FAIR. 803 



from the cocoon for several years, though, not so generally. It is 

 strangely true, however, that moth and yucca flower mature at 

 the selfsame season ; and strangest of all, it can not be shown 

 that the moth during its short existence in the perfect state takes 

 a particle of nutriment from the yucca flower no pollen, no nec- 

 tar, no stigmatic fluid. This is practically certain. Here, then, 

 is a case of " instinct " that is utterly dazzling ; it bids defiance to 

 comparative psychology, philosophy, metaphysics everything. 

 Here is a plant that can not perpetuate itself without one certain 

 strangely specialized moth ; and here is a moth that can not live 

 without that plant; and that moth deliberately cross-fertilizes 

 the flowers without receiving any nutriment from them ! Verily, 

 the botanist must rise up and say of the yucca moth what Cicero 

 said of the aged planter of orchards, "Serit arbores quse alteri 

 sseclo prosint!" and even with greater truth. This is interde- 

 pendence between the worlds of insect and plant life that baffles 

 understanding. 



Cacti, agaves, yuccas, such is the three-typed group that stands 

 out as a great division of a flora distinctively American ; unique 

 in the phase of plant development it presents; peculiar to a 

 region of strange physical aspect ; sprung directly, for aught that 

 is known otherwise, from the mystery-shrouded soil of the Aztec 

 and the cliff-dweller. And this is the splendid tribute the land of 

 the far Southwest gives to the world of science. 



HOUSEHOLD ARTS AT THE WORLD'S FAIR. 



BY FREDERIK A. FERNALD. 



THE visitor who wishes to learn what the World's Columbian 

 Exposition has to teach in regard to the domestic arts will 

 not find the exhibits in this field gathered in a separate building, 

 as are those relating to Transportation or Agriculture. He will 

 not find them entered as one class in the Official Catalogue, but 

 must search them out in nooks and corners, and will often stumble 

 upon them in the most unlikely places. 



To begin with the house itself : two specimen dwellings of low 

 cost are exhibited. Away down near the southeastern corner of 

 the grounds is a neat wooden cottage, forming part of the New 

 York exhibit, and known as the Workingman's Model Home. 

 The house, with cellar, would cost ordinarily $1,000 ; it measures 

 20X28 feet, and is designed to stand on a lot of 25X40 feet. On 

 the first floor are a hallway, living room, kitchen, bath room, and 

 storeroom ; on the second floor are three bedrooms, each with a 

 closet, and a large closet at the front end of the upper hall. The
