Show Continued from last Seeds That Of seeds that travel by we have a considerable Nearly all seeds are but some will sail having sail-like wings for this Many of the sedges have seeds resembling boats and swim with ease for long so also do the seeds of our various docks and water The common and the water plants called alisma and found the latter being quite are other We have two colors of water lilies in our high mountain white and The seeds of water lilies are said to have two outer coats with a air enabling them to float long distances aft the manner of Fruits or Plants That All the smaller round fruits and stones roll along the down the The list includes most stone fruits and many Rolling and In some cases the whole plant is adapted to rolling along the scattering its seeds as it We have the tumbling the common or and now and most the Russian Many seeds travel by sliding on the snow and ice before the All the small seeds may do This might be called One experiment station has called attention to the distances traveled by large quantities of wild and clover seeds in this Seeds That There is no difficulty in making a collection of those seeds that stick to one's clothing or to the fur of Our most common ones are the which is a branching the the prickly rag and the the bur the some of the and many of the seeds of the Seeds Carried by Seeds carried by animals are of many Those floating on that cling to the feet of water the smaller stone fruits eaten by ravens and stony fruits eaten by the robin and and then thrown up in small masses of undigested seeds eaten but not digested with the especially the small seeds of fleshy fruits like the poison and Certain little ugly water plants are found almost everywhere from the Arctic circle to An Austrian botanist examined the mud scraped from the feathers and legs of a number of wading Thirty-one kinds of sedge and rush seeds were found adhering to these showing why water plants are so widely Seeds Hidden by Many of the burrowing animals hide nuts and other seeds in their burrows and some of them are left to nut seeds and grains are thus The ants store food for winter in this and carry many weed but eat away only the or of the which later may germinate and Many fruits are like the heads of our gum plant and But many kinds show special adaptations for adhering to while other plants are sticky all either with gum or with barbed and so cling to fur or Of this class our beautiful desert with a fine white and yellow flower opening in is a remarkable type of due to hooked Significance of the It is a significant fact that most of these contrivances are now known to confer some other benefit on the plant in addition to securing the dissemination of its They often protect the fruit from being or from the cold or or from insect often the fruits are scattered for the advantage of the animals that feed on Sometimes these devices serve to attach the seed to the soil for the purpose of Most of the flowering plants exhibit contrivances for two methods of seed dispersal on for near and one for distant distribution prickly rag the even though the latter may not necessarily take burs may fall to the ground and roll a short or they may attach themselves to animals and travel a long Seeds Record As we think of the wild ducks so fond of and of how these must scatter the seeds of marsh plants and others floating on the waters in which they of the seeds that become entangled in the feathers of the shore birds and cling to their muddy feet as they arise on of the IK L K Fig SO SOME COMMON WEED

cockleburs and carrying them when we watch our industrious red ants planting seeds which they find especially adapted to their jaws by containing little crests or as we think of the flow of our rivulets and and finally of the primitive races that once traversed these regions we conclude that our present flora has had a varied and interesting history of travel and that every species is trying to colonize new ever seeking fresh fields and new Not content with their old each sends pioneers to try new so whenever exterminated or suppressed in one they are still flourishing Is Nature Some have claimed that nature is prodigal in producing so many but it is well that this is the for since not many of the seeds can find good places in which to not a few of the different kinds might As the
