The Morning Glory Bush. 119 



or error in observation, the question would then be explicable 

 ■either upon the hypothesis of unfavorable conditions for the main- 

 tenance of the species in certain localities at certain periods from 

 deficient food, epidemics, or preponderance of natural enemies; 

 or, in the case of error, time for the correction of the same. 



As any one of the causes mentioned is competent to account 

 for the absence of the species from the localities, I shall have to 

 rely upon time to point out the vera causes — be it the natural dis- 

 tribution, absence of proper food, epidemics, influence of natural 

 enemies, or error in observation. 



The larvae of any of the species enumerated are unknown to 

 me. Pupae of S. sculptilis have been observed, but unfortunately 

 I neglected to preserve any of the specimens. In color they 

 w r ere milky white, elongate and but slightly curved. They pass 

 through their transformations in the soil, near the surface. I have 

 not observed any cocoon more than the cavity formed in the soft 

 leaf-mould, beneath the prostrate plants and decaying debris 

 along water-courses. Frank E. Biaisdell.

THE MORNING GLORY BUSH, IPOMsEA LEPTO- 



PHYLLA. 



What brilliantly flowered shrubs ! How beautiful ! Great 

 masses of them, here and there, glorify the early morning of the 

 Colorado plains. The landscape for miles is, in some places, 

 beautified by these large mounds of crimson flowers amid their 

 bright green leaves. 



It is indeed a morning glory that does not twine; but, instead, 

 grows in large shrubby clumps three or four feet in diameter and 

 almost as tall as broad. However, it is an herb and not a shrub; 

 for in winter no trace of it is to be found above ground, except 

 perhaps the dry and withered twigs of the previous summer. 

 Underground, its dimensions are enormous; for it has an immense 

 roundish root that stores up sufficient nourishment so as to enable 

 the plant to make a growth in early summer rivalling that of 

 Jack's famous bean stalk. 



The flowers are numerous and larger than an ordinary morn- 

 ing glory; the leaves are long and narrow, glistening in the sun- 

 light. Certainly the plant would well repay cultivation and seems 

 especially adapted to the open lawn where a single plant when 

 well grown would take the place of a whole bed of flowers.

GEM ARROW POINTS 



(From the Great Divide, March, 1890.) 



Nearly everyone is more or less familiar with the common flint 

 arrow and spear heads turned up by the plow or dug from the 

 mounds of the ancient red men or .aborigines of America; but
