BOARD OF HORTICULTUHE, MONTANA. 13 



Rule 14. It is hereby ordered that all green fruits and all citrus fruits 

 found for sale in Montana, shall be inspected and if found free of any 

 disease or infection, shall be branded "Inspected and Passed," but if found 

 to be infested with injurious insects or disease, shall be condemned and 

 destroyed by burning. 



Rule 15. For the inspection of all green fruits and citrus fruits, a fee 

 of two (2) cents per box or package, with a maximum charge of |5 for each 

 separate lot inspected. 



Rule 16. All fees collected for inspection and fumigation shall be turned 

 over by inspectors to the secretary of the board, and shall be paid out on 

 the order of the president and secretary and member of this board for the 

 district in which said fees are collected. 



Rule 17. It shall be the duty of each person or corporation offering to 

 sell or selling and delivering any nursery stock, trees, plants, vines, scions, 

 cuttings, etc., within the State of Montana to place on each and every package 

 so sold and delivered a label or card stating whether or not said trees, plants, 

 vines, scions, cuttings, etc., were grown in the State of Montana or otherwise. 

 By fumigation is to be understood treatment with hydrocyanic acid 

 gas. This treatment should be done as follows: All nursery stock to be 

 treated should be placed in an air-tight tent or box. For every 100 cubic 

 feet of space in box or tent, take one ounce (avoirdupois weight), of fused 

 potassium cyanide, 98 per cent, strength, preferably in lumps about the size 

 of a walnut; one and one-half ounces commercial sulphuric acid, best 

 grade, and two and one-fourth fluid ounces of water. First place the water 

 in a three-gallon vessel (which may be of glazod earthenware) ; to this 

 add the acid and finally the potassium cyanide. (The cyanide would better 

 be enclosed in a small paper bag in which a hole is torn). Immediately 

 close the doors or openings, taking all precautions against inhaling the gas., 

 which is one of the most violent poisons known. After leaving box or tent 

 closed for 40 minutes, open all doors and allow at least one hour for thor- 

 ough ventilation before attempting to remove the stock. No injury is caused 

 to nursery stock if the gas is left in more than 40 minutes.
