their changing from the caterpillar to the chrysalis. Every fly 

 has a different proceeding. 



Always walk with a box or two in thy pocket, and then thee art 

 provided ; for oftentimes, when one least expects, a curious thing- 

 is seen, but perhaps lost or broke for want of a proper conve- 

 niency to secure it.

Friend John : 



I have a strong opinion that our misletoe may be propagated 

 with you, in the manner I have often tried with success ; and then, 

 again, yours may be with us. I have sent some berries in a box. 



My method is to choose the smoothest part of some branch of 

 an apple tree, and thereon I bruise the berry, but not the seed. 

 By virtue of the glutinous matter about it, it will stick to the bark. 

 The north side of the branch is best. If it sticks but loosely at 

 first, yet in a few days there is a mutual attraction on both sides, 

 and the seed will be found closely stuck to the bark. It is very 

 pretty to see the progress of vegetation, and how the seed pushes 

 forth two roots, which insinuate themselves into the bark. 



Its natural way of propagation is by a thrush, that is fond of 

 the berries, and lives mostly on them whilst they last.

It is surprising to think the seed should preserve its vegetating 

 quality through the heat of the intestines of the bird, and the 

 glutinous part with it, that wherever it lights it sticks fast. But 

 such is the order of Providence ; and an evidence of the great 

 wisdom and power of the Creator, to whom all things are possible. 



Pray send me some of your berries, for no doubt your misletoe 

 differs from ours ; and please to send a specimen of what sorts 

 you have. We have but one with us ; but with this difference, 

 some are male, and some female that bear berries, others none, 

 but the farina to impregnate the female blossoms. I have a pretty 

 deal on sundry trees in my garden ; for I try all sorts, by the 

 method prescribed. Being an evergreen, it makes a pretty show 

 in winter. As this is a secret, thee may make it so, for few believe 

 it, but it is fact. ***** 



I am thine, 



P. COLLINSON.
