Milky Way. Over in the cast, as if 

 in pursuit, come the great summer 

 stars and constellations, led by Spica 

 in the Virgin, Arcturus in the Bear- 

 Driver (Bootes), and Vega in the Lyre. 

 Between the two hosts the central part 

 of the sky is relatively barren, Leo 

 high in the south, and the Great Dip- 

 per nearly overhead, being the only 

 constellations to attract much atten- 

 tion there. The huge serpent, Hydra, 

 with his diamond-shaped head under 

 the Beehive cluster in Cancer, stretches 

 eastward beneath Leo, Crater, Corvus 

 and Virgo, but with the exception of 

 Alphard he has no bright star. Coma 

 Berenices, above Virgo and between 



Leo and Arcturus, gleams with a sil- 

 very lustre derived from its multitude 

 of small stars, and presents an admir- 

 able object for the opera-glass. A 

 little later in the evening, as Sirius 

 sinks behind the western horizon, Vega 

 begins to glitter with diamond bright- 

 ness above the north-eastern horizon. 

 Spica, in the meantime, advances from 

 the east, and proclaims herself the 

 queen-star of the Spring, for while she 

 is less brillant than Arcturus above 

 her, she possesses a singularly pure 

 white ray, which is hardly matched 

 in beauty by that of any other star 

 in the heavens.

New York, March 22, 1909. 



To The Patrons of "The Mineral 

 Collector :" 

 It is with pleasure I anounce that I. 

 have arranged with Mr. Edward F. 

 Bigelow, editor of The Guide to Na- 

 ture, to introduce a department, to 

 be edited by myself, and thus make 

 that publication the successor of The 

 Mineral Collector. All unexpired sub- 

 scriptions are to be filled out by that 

 publication. We hope all persons 

 whose subscriptions have expired will 

 send in their renewals to me without 

 delay. As the subscription of The 

 Guide to Nature has been reduced 

 (beginning April 1909, from $1.50 to 

 $1.00 and is a much larger and better 

 publication than The Mineral Collec- 

 tor,) we hope all our subscribers will 

 use their best endeavors to aid in se- 

 curing additional subscriptions. YVe 

 would also like to secure notes, origi- 



nal papers and descriptions of trips, 

 accompanied with photographs, where 

 possible for this department. I thank 

 my subscribers for their support in 

 the past, and request a continuance of 

 the same for The Guide to Nature, 

 as successor to The Mineral Col- 

 lector. 



Very truly, 



Arthur Chamberlain, 

 Editor and publisher of "The Mineral 

 Collector." 



P. S. — Volume two of The Guide to 

 Nature starts with the April, 1909, 

 number. Every subscriber sending 

 $1.75 can secure the first two volumes. 



To the Constituency of The Mineral 

 Collector: 



The Guide to Nature and The Agas- 

 siz Association, represented by it, cor- 

 dially welcome you to our fellowship 

 in the study and love of nature. We 

 realize that minerals are of intense 

 interest to the careful student, and are
