LA BORA TOR Y APPLIANCES. 



For Spring botany 



Our line of Botanical Supplies is not the regu- 

 lar stock which is usually found on the market. 



Our 



Botanical Mounting Paper 



is a fine quality of linen ledger paper manufactured especially for 

 us after our own specifications with a view to producing a pure 

 white sheet which will retain its whiteness and strength with age, and 

 have that much desired stiffness which makes the sheet stand out 

 firmly when held by one end for inspection of the specimen. Our 



Genus Covers 



are likewise made especially for us, and in addition to being made 

 of the finest fiber, have a superior writing finish. We likev/ise have 

 our 



Driers 



made to order to secure that bibulousness and weight which add to 

 their effectiveness. Having these papers made in quantity enables 

 us to quote a very satisfactory rate on large orders for the herbaria 

 of universities, colleges, and other institutions. Our prices on small 

 lots for private use will be found as low as any, and you get an extra 

 quality of paper besides. In the matter of the 



fasGulum aim Plant Press 



We have advantages to offer in the convenient 

 construction, neat workmanship, durability, and 

 moderate price. Place orders early and do not 

 fail to get estimates from us before ordering 

 elsewhere.
