1 87 BOTANICAL GAZETTE. 



ponding "eyes" on the roller is used. As the under charts are wanted 

 the upper ones can be thrown over the top and out of the way. 



A word in regard to the preparation of the India ink. If you follow 

 the ordinary directions, viz: to rub down the quantity needed in a 

 porcelain dish, after grinding away till your arms ache, you will have 

 enough perhaps to outline one illustration and probably half of that 

 will evaporate before you are ready to use it. Instead, take about half 

 a stick break it into pieces the size of a grain of wheat and allow it to 

 soak over night in just enough water to cover it. When you are ready 

 to use dilute until it will just leave a perfectly black mark. If at all 

 lumpy rub to a smooth paste with a flat ended stick. Apply with a 

 camel's hair or sable brush— one tapering to a fine point will be found 

 easiest to handle. Let me assure any who care to attempt the manu- 

 facture that it takes very little artistic talent, very little time and very 

 litde trouble to produce results that will astonish the maker. (No sar- 

 casm ) These charts are cheap, portable and efficient ; qualities j^os- 

 sessed by none of the more elaborate ones of the publishers. I shall 

 be glad to give any further details of construction if any one so 

 desires.— C. R. Barnes, Purdue Univ., LaEayette, Lid. 



The Flora of Essex County, Massaclmsetts, John Robinson, 



Essex Institute, Salem, iS8o.— An elegant Catalogue of 200 pages. 

 Those who are familiar with Prof Robinson's methods will not need 

 to be told that this Catalogue is a most thorough and admirable work. 

 No finer Catalogue has been published since Paine's model catalogue 

 of the plants of Oneida County, N. Y., and could the lamented Oakes, 

 to whose memory it is so gracefully dedicated, have lived to see this 

 tribute to the flora of a region "wnere he was born, and where he 

 loved to botanize," his ])ieasure would have been very great indeed 



Tracy's modest "Studies of the Essex Flora" was only partial in 

 Its character, being limited to the vicinity of Lynn, and containing 

 only the flowering plants of that region ; but the present Catalogue 

 covers the entire County, and contains the lower, as well as the higher 

 orders of ]jlants. 



Combining within her limits seashore and woodland of varied 

 character, Essex County offers rare attractions to a botanist, and how 

 well sea-shore and wood land, meadow and hill have been gleaned for 

 treasures this si)lendid record attests. 1694 species and 140 varieties 

 are enumerated representing 115 orders. 



The remark.ible resemblance between the wood lands of Essex 

 and those of New Hami^shire has often been noticed by visiting bot- 

 anists, and it is not surprising to find recorded here many plants com- 

 mon to both regions. 



The writer has ])assed many pleasant hours in the Essex woods 

 with the author, the recollection of which he will long cherish, and it 

 gives hun much jjleasure now to bear witness to the zeal and fidelity 

 with which the author has devoted himself to tliis work of the "Essex 

 Flora," the completeness with which it has been consummated, and 

 the very elegant form in which it is presented. 



Full credit is given to all who have aided the author in any way,
