Fifty Common Trees op New Ycrk 7 



3. Fruit. Fruit and seeds need not be pressed, but should be kept 

 in envelopes or paper sacks with the name of the tree carefully written 

 on the outside. 



Mounting the specimens on paper 



Standard covers 9 by 12 inches will be furnished by the Department 

 of Forestry for the collection. Therefore, the paper for mounting should 

 be not larger than 8% by liy 2 inches. Heavy white paper or light 

 cardboard, either white or buff, is to be preferred. Have also on hand a 

 supply of Dennison's gummed-cloth mending tape iy± inches wide. Cut 

 across the tape, making little strips about % inch wide. Punch holes in 

 one margin of the paper to correspond with the holes in the covers fur- 

 nished for the collection. 



With these materials ready, remove the specimens from the press. 

 Place a piece of the mounting paper on a flat surface with the punched 

 margin to the left. This will make all your specimens appear on the 

 right-hand page as one opens the book. Do not mount anything on the 

 other side of the sheet. 



Place the leaf on the portion of the sheet nearest the center, leaving 

 the twig and the seed for the outside, and at least 2 inches of space below 

 for the name of the tree and its principal uses. In cases of larger 

 leaves, especially compound leaves, only one can be placed on the sheet, 

 but two averaged-sized leaves can be mounted, one above the other, to 

 advantage, one showing the upper surface and the other the lower sur- 

 face. (Note the difference in the case of black oak.) Do not fail to have 

 all of the leaf stem along with the leaf. 



To hold the leaf in place, paste strips of gummed cloth across the 

 stem and the points of the leaves (figure 1) . Use as few gummed strips as 

 possible ; too many strips spoil the neatness of the mount. In the case of 

 the needle-leaved trees, particularly spruce, fir, hemlock, and larch, it 

 will be necessary to glue each needle to the mounting paper, otherwise 

 the needles will eventually fall off and leave the twig bare. 



There is an easy way to spread the glue over the needles. First spread 

 a very thin coating of the glue over a piece of paper. Then place the 

 needles on the glued paper and press down gently until every needle has 

 come in contact with a small amount of the glue. Now shift the needles 

 onto the paper on which you wish to mount them, press them down gently 

 and place a weight on them to hold them in place while the glue is dry- 

 ing. In this way, it is easy to stick every needle fast to the mounting 

 paper.
