have the means of transplanting or colonifing their 
tribes almoft over the furface of the whole earth ; 
fome feeds, for inllance, grapes, nuts, fmilax, peas, 
and others, whofe pulp or kernel is food for animals, 
will remain feveral days without being injured ia 
ftomachs of pigeons and other birds of paffage ; by 
this means fuch forts are dift ributed from place to 
place, even acrofs feas ; indeed fome feeds require 
this preparation by the digeftive heat of the ftomach 
of animals, to dhTolve J and detach the oily, vifcid 
pulp, or to foften the hard fhells. Small feeds are 
fometimes furnimed with rays of hair or down ; and 
others with thin light membranes attached to them, 
which ferve the purpofe of wings, on which they 
mount upward, leaving the earth, float in the air, 
and are carried away by the fwift winds to very re- 
mote regions before they fettle on the earth ; fome 
are furnimed with hooks, which catch hold of the 
wool and hair of animals palling by them, and are 
by that means fpread abroad ; other feeds ripen in 
pericarpes, which open with elaftic force, and moot 
their feed to a very great diftance round about ; 
fome other feeds, as of the Moffes and -Fungi, are 
io very minute as to be invifible, light as atoms, 
and thefe mixing with the air, are wafted all over 
the world. 
The animal creation alfo excites our admiration, 
and equally manifests the almighty power, wifdom, 
and beneficence of the Supreme Creator and Sove- 
reign Lord of the univerfe ; fome in their vaft fize 
and ftrength, as the mammoth,, the elephant, the 
whale, the lion, and alligator ; others in agility; 
others in their beauty and elegance of colour, plu- 
mage, and rapidity of flight, having the faculty of 
moving and living in the air ; others for their imme- 
diate and indifpenfable ufe and convenience to man, 
ill furnxming means for our clothing arid fuftenance,
