384 CALENDAR OF OPERATIONS, [chap. xii. 
Judas tree, Edwardsia, &c., among the trees. 
The Pseonia Moutan will likewise expand 
its magnificent blossoms; and the spring 
heartsease will be coming into flower, as will 
the Nemophilla insignis, and several of the 
other Californian annuals. 
In the kitchen-garden, the operations 
continue nearly the same as the last month. 
Peas and beans may be sown for the late 
crops, and spinach, &c. This is the proper 
season for sowing kidney-beans. If the 
first crop of peas has not been staked, it 
should now be done, and the tops should be 
taken off the common beans; both may also 
be hoed up. The blossoms of the fruit-trees 
should be examined, and those attacked by 
insects should be instantly removed, and the 
insects they contain destroyed. All leaves 
that are found rolled up should be taken off, 
and destroyed. In the park and pleasure- 
grounds, oak-trees are generally felled in 
May, because the movement of the sap at 
this season makes the bark separate more 
easily from the wood.
