 prevention rather than to combatting' them after they 

 have made their appearance. 



Tent Caterpillar. -If the keen-eyed horticulturist will 

 walk through his orchard during the winter months 

 when the trees are bare, he will now 

 and again perceive a twig- that has a 

 peculiar swelling, and he will see 

 that the swelling is caused by a 

 band of small eggs carefully laid 

 side by side and well covered over 

 by a waxy substance. These are the 

 eggs of the apple tent caterpillar, 1 

 which are ready to hatch with the 

 first days of spring. The almost 

 microscopic caterpillars will go out, 

 ready to feed upon the opening buds. 

 Xow if the horticulturist will apply 

 his pruning-knife and remove the 

 twigs and cast them into the fire, lit' 

 will have coped very successfully with one of his i 

 enemies. If, on the contrary, however, he is spending 

 his time in other pursuits at this winter season, there 

 will appear early in the spring in his orchard great 

 clusters of caterpillars well housed in large webs in 

 the forks of his trees. They will go from this house
