Some practical suggestions concerning- seed germination, . I I In 



I izona Sta. Bui. 51, pp. 586 541)- Experiments were made to study the effect of 

 mechanical and hot water treatmenl orj the germination of the highly moisture- 

 resistant seeds of a number <>i' semiarid plant-. The author found thai when the 

 hard resistanl seed coats were rendered permeable to water by scratching, cutting, 

 or grinding, the germination of the seeds under normal conditions took place imme 

 diately. In the tots with hoi water treatmenl upon several kinds of seeds, Buch as 

 locust, acacia, and mesquite, the besl results were obtained by placing the seeds in 

 hut water for 2 minutes, then soaking them in lukewarm water for 12 to 24 hours 

 moving the swollen ones, and again subjecting the resl to the treatmenl until they 

 swelled. Four lots of 50 catclaw seeds each, immersed for different lengths of time 

 in water at B5 to 88 C. gave the following results: One minute immi jeeds 



swollen and 33 germinated; 2 minutes. 27 swollen and 36 germinated; •"> minutes, W 

 swollen and 41 germinated; and 4 minutes, l<> swollen and 33 germinated. 



A list is given of seeds which weir successfully germinated by stratifying them 

 during the winter and planting early in the spring in well-prepared soil.

Vegetable gardening, S. B. Greek (St. Paul: Webb Pub. Co., 1905, 7. ed., pp. 

 952, figs. 128). -This well-known hook on vegetable gardening for northern latitudes 

 has been revised to Borne extent and enlarged. A number of test questions have 



been included, which Letter adapts it for use in the class room, and a different 



arrangement has been made in the grouping of the vegetables treated.
