lopes are not only superior in quality, but also cost about one 

 fourth as much as those obtained from dealers in botanical sup- 

 plies. These envelopes should be made from a good quality of 

 bond paper. This paper comes in three sizes : 17 X 22, 17 X 28, 

 and 19 X 24 inches. The 17 X 22 size cuts into nine pieces, each 

 5f X 7i- This can be folded into an envelope approximately 

 2 \ X 6 ; or, folding the other way, 3 \ X 4i • Larger envelopes 

 are sometimes needed, and these can be cut from the 19 X 24 

 sheet. Cutting three times each way, the resulting piece is 

 X 8 inches. This folds into an envelope either 3 X6f or 

 3f X 5 inches. 



" Labels can be printed most cheaply by having the work done 

 at some printing shop that makes label-printing a specialty. 

 Here they will be printed at approximately a third of the price 

 charged by the local printer. The labels are fastened to the 

 envelopes by white glue made about as thick as thin cream. " 



The thirty-first annual report of the North Carolina Agricul- 

 tural Experiment Station contains a descriptive list of more 

 than fifty of the common plant diseases of that state, by F. L. 

 Stevens and J. G. Hall, illustrated by ten plates. 



A discussion by Mr. Fred J. Seaver of " Color Variation in 

 Some of the Fungi" (Bull. Torrey Club 35: 307. 1908) calls 

 attention to certain marked changes of color which occur in some 

 species. The several illustrations, which are taken from the order 

 Hypocreales, show the confusion resulting from the descrip- 

 tion of new species in this order, when based on color alone. 



Under the title " Studies in North American Peronosporales — 

 III" (Bull. Torrey Club 35: 361. 1908), several new and note- 

 worthy species are listed by Professor G. W. Wilson. No. IV 

 of the same series of papers (Bull. Torrey Club 35: 543. 1908) 

 consists of a host index of the commonly recognized American 

 species of the order.
