 the agricultural society of Trinidad in Sei)tember, 1907, in which the author 

 offers numerous susjxestions with rejiard to the proper pruuins of trees in tlie 

 nursery, at planting time, and subsequently, with special reference to the pro- 

 tection of tbe tree from attacks of canker. Suggestions are given with i-egard 

 to the use of cover crops and fertilizers. 



The art and craft of garden making, T. H. Mawson (Lomlou. l!)i)7. pii. 

 XX-\-310, pis. 3, fiffx. 200). — In this worlv the author deals with the various 

 phases of garden designing. Consideration is given to the selection of the site 

 and its treatment, fences and gates for gardens and i»arks, entrance gateways, 

 carriage courts and drives, terrace and flower gardens, lawns, walks, snnnner 

 houses, trellis work, garden furniture, tlie treatment of water fountains, lakes, 

 streams and ponds, conservatories, greenhouses, vineries, fruit houses, kitchen 

 gardens, orchards, avenues, hedges, planting for landscai)e effect, trees, shrubs, 

 conifers, hardy climbers, roses, hardy perennials, aquatic plants, and ferns. 

 Lists are given of the best varieties for the various forms of planting, and the 

 text is accompanied with photographs, sections, sketches, and detailed plans 

 illustrative of various styles of garden designs.

 practical gardening edited by II. Roberts and deals with the construction and 

 develoitment of rock, Alpine, water, bog, and marsh gardens, with lists and

The production of Easter lily bulbs in the United States, G. W. Oliver 

 {U. »S'. Dcpt. Ayr., Bur. Plant Indus. Bui. 120, pp. 2'i, pis. J,, flys. 3).— Although 

 Bermuda is at pi'esent the main source of supply of Easter lily bulbs for the 

 United States, in many cases the plants grown from Bernuida bulbs in this 

 country are so greatly diseased as to be i)ractically un.salable. Previous experi- 

 ments undertaken to develop the l)nll) industry in this country ai)pear to 

 demonstrate the impossibility of producing bulbs asexually as is lu-acticed in the 

 Bermudas and Japan. 



For several years the Bureau of Plant Industry has endeavored to establish 

 the bulb industry in this country through propagation by seedlings, sinc(> in 

 jtrevions work of the Bureau (E. S. II., 15, p. 259) it w^as discovered that seedling 

 I)lants were ju-actically free from the disease. A large number of seedlings were 

 grown and distributed on the Pacific coast and Florida. The present l)ulletin 

 summarizes the results of this work to date. Conclusions based on these trials 

 are given as to localities ada]»ted for lily bulb growing, varieties, adv:intages of 

 seedlings over ])lants )iroduced asexually, selection of seed bearers and seedling 

 tyi)es for propagation, togetlier with cultural directions, including preparation 

 of the soil and i)lanting operations, pollination, seed scnving and transplanting. 

 Comparative data are also given on ranges of temperature and i>recipitation at 

 Prospect and Hamilton, Bernnida, as compared with lily-growing regions of the 

 United States. 



The experimental work now being conducted on the Pacific coast jiromises suc- 

 cessful results. In addition to the elimination of disease, the seiMlling method is' 

 found to be quicker than propagation by scales. or from small buli)s. Fnder 

 favorable conditions plants can be depended upon to give bulbs of salabl<> size 

 the first vear. The usual sizes secured are from 5 to 7 in., but a consider-
