138 BEES AND BEE-KEEPING. 



mand for that purpose. The linden, or bass-wood 

 {tilia Americana), produces honey to a large amount. 

 All of these varieties of trees should "be extensively 

 cultivated, both as shade and ornamental trees, as 

 well as for their timber and the vast quantities of 

 honey they yield. Sumach also produces honey

The common black mustard is one of the most 

 valuable plants to cultivate as a pasture for bees ; it 

 is easily raised, by simply sowing it on ground when 

 well plowed and pulverized by harrowing smooth, 

 and then brushing it in with a light brush or very 

 light harrow. It should be sown early in the spring, 

 on good ground. The seed is now worth from eight 

 to fourteen cents per pound in Pittsburgh and other 

 cities, for grinding and preparing for table use ; at 

 these prices it will pay well as a field crop, being 

 worth more per bushel than clover seed. I was told 

 recently by a man largely engaged in grinding and 

 preparing spices, that it is quite difficult to get a 

 supply of good mustard ; so scarce is it, that it be- 

 comes necessary to import it from Europe. He also 

 informed me that this black mustard is of greater 

 value than the white. Those interested in bee-keep- 

 ing should give the cultivation of mustard some 

 attention. As a bee pasture it has few superiors,
