3 o THE SCHOOL GARDEN. 



course he hedged in safely in order to be guarded 

 against injury. The seeds required can be purchased 

 by several united parishes, and if necessary by a whole 

 district (Bezirke), so that each parish will have to con- 

 tribute but a few kreutzers. In many, probably in most 

 cases, the seeds and plants will be given by public- 

 spirited men and societies, or by other school gardens. 

 Thus, in a surprisingly short time many new, useful plants 

 will be contributed and acclimated, whose domestica- 

 tion would otherwise be difficult and perhaps impossible, 

 unless some large landed proprietor in the neighborhood 

 makes a beginning. New kinds of cereals, maize, saf- 

 fron, potatoes, hops, the different kinds of table pump- 

 kins so little estimated at their true value, clover (in 

 Hungary), and a series of technical and economical and 

 commercial plants can thus be introduced into many 

 places with little trouble and little cost. Although the 

 more important commercial plants, (that. is, medicinal 

 plants,) and those that yield oil, colors, spinning material 

 and roots, give a specially good revenue, the difficulty 

 of their introduction has stood in the way of their gen- 

 eral spread, while the consequently little revenue they 

 have brought under these circumstances has led to the 

 abandonment of the endeavor after a few trials. 



THE MICROSCOPE AS AN AID. 



The microscope, which naturally comes into the ser- 

 vice of the public school, will do its part to teach the 

 pupils how to know many dangerous diseases that assail 

 cultivated plants, such as wheat, potatoes, etc., and will 

 make known many scarcely visible insects that are the 

 enemies of agriculture and must be fought.
