Hortus Gramineiis Woburnensis. 67 



Eggers' plan for cultivating the Truffle is noticed ; we have 

 before (vol. i. p. 320.) reviewed the pamphlet, and shall revert 

 to it in giving some " hints for experiments." 



Having now gone through M. Poiteau's introductory re- 

 view, we shall pause till some future number, when we shall 

 look over the body of the work, and extract whatever we con- 

 sider will be interesting to our readers ; and more especially any 

 information not to be found in our Encyclopaedias of Garden- 

 ing and Agriculture; or in the preceding numbers of this 

 Magazine.

We are desirous of introducing the first of these works to 

 our agricultural readers, as containing a vast quantity of 

 original and important matter on a branch of agriculture very 

 imperfectly understood by practical men. The high value 

 which we set on the Hortus Gramineus is evinced by the 

 copious extracts and frequent abridgments which we have 

 made from it in our Encyclopaedia of Agriculture. 



Pasture grasses, like woods, cover naturally so large a por- 

 tion of the earth's surface, and, when they are destroyed, so 

 freely re-produce themselves, that their artificial propagation 

 and culture was not had recourse to till a late period in the 

 progress of agriculture. Grasses are the most universal of 

 plants ; they exist in greater numbers than any other tribes, 

 both in the coldest and in the hottest climates. In the two 

 extremes of temperature the annual species are prevalent ; and 

 in the milder regions, where the winters are short and the 

 heat of summer not so great as to burn up all surface vege- 

 tation, the perennial species are most numerous. The pastures 

 of the greater part of America and Russia, as well as of 

 Egypt and Persia, are composed of the first ; and those of
