The State of Illinois has now undertaken by leg-islative enact- 

 ment to prevent, so far as reasonably practicable, the introduction, 

 maintenance, and spread in this state of the fungus and insect 

 parasites of fruit and ornamental trees and shrubs ; and as an 

 important feature of this program of state control a system of nur- 

 sery inspection has been established substantially identical with 

 that now maintained in many other American states. It is the 

 object of this inspection to insure as fully as possible the freedom 

 of nursery stock, as delivered to customers, from injurious insect 

 and fungus pests likely to continue as a cause of loss or damage in 

 the orchard or on the premises of the purchaser. 



A distinction must be made in practice between those insects and 

 fungous diseases injurious to the property of the nurseryman, but 

 from their nature not likely to be conveyed by the dormant tree 

 stripped of its leaves, and those which continue on the affected tree 

 or shrub through the winter in a condition to revive and spread with 

 the renewal of growth after transplantation. The nursery inspec- 

 tion is made under our law primarily for the protection of customers 

 of nurserymen, and only secondarily for the benefit of the nursery- 

 men themselves; and on this account, first and most careful atten- 

 tion is naturally given by our horticultural inspectors to those 

 pests which are capable of being distributed through the nursery 

 trade. A slight and seemingly insignificant appearance of an 

 insect or fungus of this description in the nursery rows may be far 

 more important from the inspector's point of view than an extraor- 

 dinary outbreak of some other form highly injurious in the nursery 

 itself, but left behind when the stock is shipped. 



It is greatly to the interest of the nurseryman that he should 

 be able to detect and recognize on their first appearance all those 

 injuries and diseases which by conveyance to his customers must 

 seriously affect his trade, and which, by rendering his premises 

 liable to an official quarantine, may embarrass his operations at a
