Process Glue, manufactured by the same company. The mix 

 is made on the plate, the Improved Process Glue being spread 

 on the plate and then thinned by wetting the brush with Special 

 A Tin Paste. Occasionally the glue is renewed, but not often. 

 In general practice, the use of about one-fourth Improved 

 Process Glue and three-fourths Special A Tin Paste seems to 

 give the best results. 



Experienced mounters will of course vary their methods ac- 

 cording to circumstances in the light of previous experience, 

 and with reference to the general type of material being mounted. 

 I do not hesitate in recommending Special A Tin Paste, either 

 alone or combined with Improved Process Glue, as being defi- 

 nitely superior to any type of ordinary fish glue I have been 

 able to secure.

A NEW CATCHFLY FROM THE SOUTHEASTERN 



STATES 



John K. Small 



Recent studies, both in the field and in the herbarium, have 

 brought an additional catchfly to our attention. Concerning 

 the recognition of this plant as a new species. Dr. Wherry 

 writes me as follows: "The common rock-catchfly of the eastern 

 states, Silene caroliniana Walter, grows typically on shaly or 

 gravelly slopes, where the soil reaction is usually distinctly acid. 

 I was therefore rather surprised to see, while on a trip across 

 Kentucky a few years ago, what appeared from the train win- 

 dow to be the same plant thriving on limestone ledges in the 

 Interior Low Plateaus Province. Later on, during a trip in 

 search of Phlox Stellaria along the Kentucky River near Camp 

 Nelson, south of Lexington, under the guidance ot Professor 

 Frank B. McFarland of the University of Kentucky, oppor- 

 tunity to examine the Silene more closely presented itself, and 

 it then seemed that it might possibly be new. I am accord- 

 ingly sending to you these notes upon it, because if it is a new 

 species you will wish to include it in your forthcoming Manual 

 of the Flora of the Southeastern States."
