culture for their support, and less than i^ cents for each of 

 the 60,000,000 of our people who consume the products of our 

 farms. The farming lands, farm implements and live stock of 

 the country are estimated to be worth $12,000,000,000. The 

 experiment stations cost us, therefore, about $6.25 a year for 

 every million dollars invested in agriculture. Or, reckoning 

 the annual value of the products of our farms at $2, 200, 000,000, 

 we are now spending about 33^ cents for every $>i,ooo worth of 

 products in an attempt to increase the value of those products 

 in future years. 



2. Statistics of the Vegetable Kingdom. 



There are 200 natural families or orders of flowering plants, 

 about 7,600 genera, and about 100,000 species are known and 

 described. The flowerless plants are much more numerous 

 than the flowering plants, both in individuals and species. 

 Ferns, moss, mushrooms and many smaller or even microscopic 

 fungi, lichens and sea-weeds are flowerless plants. 



The Ranunculaceae or Crowfoot family includes over 1,200 

 species of plants, inhabiting all parts of the world. The 

 clematis, marsh-marigold or so-called cowslip, columbine, 

 adonis, buttercup Christmas rose, love-in-the-mist, larkspur, 

 aconite and paeony are members of the Crowfoot family. The 

 family comprises 30 genera. 



There about 100 species of clematis known. 



About 40 distinct species of delphinium or larkspur are de- 

 scribed, few of which are cultivated, however. 



It is supposed that there are about a half-dozen true species 

 of paeonies known, although many supposed species have been 

 described. 



The Magnolia family comprises about 70 species of trees 

 and shrubs. Of these, 14 are magnolias proper, of which 6 

 are native of Japan, China or the Himalaya region, and the 

 remainder are North American. The lulip-tree, of which but 

 a single species is known, belongs to this order. 



The Nymphaeacese or Water Lily family contains 8 genera
