definite figures at hand, showing the 

 cost per square foot of bed space for 

 the three kinds of construction, namely, 

 raised wooden benches, solid beds with 

 walls of concrete sixteen inches high and 

 four inches thick, and raised beds with 

 iron frames apd tile bottoms. The rela- 

 tive cost is: For the wooden benches, 

 12^ cents per square foot of bed 

 space; 11 cents for the solid beds with 

 concrete walls, and 17 cents per square 

 foot for the iron frame benches with 

 tile bottoms. 



The cost per plant for carnations is 

 9 cents per plant for the wooden benches, 

 8 cents for the solid beds with concrete 

 walls, and 12 cents for the iron frame 

 benches with tile bottoms. 



The cost per plant for violets is 6 

 cents for the wooden benches, 5*4 cents 

 for the solid beds with concrete walls, 

 and 8.6 cents for the raised beds with 

 iron frames and tile bottoms. 



Thus it appears that, taking the first 

 cost of construction, the solid beds with 

 concrete walls are the cheapest. There 

 is no question as to their durability. 

 Wooden benches under ordinary construc- 

 tion will begin to rot out the second year 

 and by the third or fourth year will have 

 to be in large measure replaced. 



I have probably now devoted all the 

 time necessary to the construction of 

 the houses and would next invite atten- 

 tion to an important factor in the pro- 

 duction of any crop under glass and es- 

 pecially the violet, namely, the soil.

Red spider is sometimes bothersome, 

 but it can be kept in check by proper 

 syringing. Snails and woodlice are also 

 injurious, but can be trapped with hol- 

 lowed potatoes set between the pots, or 

 with lettuce or cabbage leaves. 



If it is possible to do so, it is well to 

 empty the greenhouse each year for a 

 few days for the purpose of painting, 

 etc. At this time the house may be 

 fumigated with a double strength of 

 hydrocyanic acid gas to kill all insects. 

 If the insects are very troublesome, 

 hydrocyanic acid gas may be used in 

 safe quantities while the plants are in 

 the house. 



Cattleyas are sometimes injured by 

 what is known as black spot. This is 

 invariably caused by too much shade, 

 overwatering or by syringing too late 

 in the afternoon. The foliage of the 

 plants should be dry before evening. 

 However, syringing should be indulged 

 in every bright day to prevent insects 

 from getting a foothold. Give plenty 

 of ventilation whenever possible and 

 there will be little danger from black 

 spot. 



Buyins: Stock. 



By a careful selection of species and 

 varieties a constant succession of bloom 

 may be maintained. The best- way to 

 purchase cattleyas, if for a large collec- 

 tion, is by the case, just imported. In 

 this way many fine varieties are secured, 

 including the white, or albino forms. 

 When only a few plants are wanted it 

 it best to buy some unestablished plants 

 from reputable dealers, and in this way 

 there is a chance of getting some excep- 

 tional varieties. After the plants have 

 once flowered with the dealer he is able 

 to select the finest forms to sell at high

prices to those who are eager to secure 

 the best that the market can afford, and 

 for this reason the unestablished plants 

 are most desirable. 



The heavy shipments of cattleyas from 

 the tropics during the last few years, 

 and the limitation of the natural sup- 

 ply, will soon cause the prices to ad- 

 vance, and as the demand for cattleyas 

 is increasing greatly each year we may 

 expect the price to advance at almost 

 any time. However, there need be no 

 great concern for the cattleya supply 

 of the future. Cattleyas are being raised 

 from seed extensively in Europe and in 

 this country. The high prices now ob- 

 tained for hybrids will soon be a thing 

 of the past. They will soon be within 

 the reach of those with a moderate purse. 

 The chief advantage in having a collec- 

 tion of hybrids is that they have no de- 

 cided period of rest. They bloonl more 

 than once each year, and for this reason 

 are cultivated with greater ease.

Regulation of Moisture. 



With the brighter days and more dry- 

 ing atmosphere, a much more plentiful 

 supply of water will be needed to keep 

 the plants in a healthy, growing condi- 

 tion. Not only is more moisture at the 

 roots needed, but more atmospheric 

 moisture is also necessary. The amount 

 of atmospheric moisture must be judi- 

 ciously regulated. In this the weather 

 conditions must be taken into considera- 

 tion. On bright, warm days it would be 

 hard to overcharge the atmosphere, as 

 it would be necessary to have a good 

 deal of air on the houses to keep the 

 temperature suflBciently low, but the 

 moisture should be so applied that it 

 will be pretty well dried out before the

time the house has to be shut down, so 

 as not to have too humid an atmosphere 

 over night. On dull, cloudy days little 

 sprinkling of the passageways or benches 

 will be needed. On such days there is 

 usually sufficient humidity in the air so 

 that it is unnecessary to create any arti- 

 ficially in the house. 



On the other hand, an atmosphere 

 overcharged with moisture is productive 

 of fungous diseases, which often prove 

 quite troublesome to the grower of to- 

 matoes indoors. A disease known as 

 spot is the most prevalent, more so in 

 the late spring and early summer months 

 than through the winter. This is un- 

 doubtedly a fungus, which breaks out in 

 yellow spots, usually on the older leaves, 

 and if not checked will soon spread and 

 destroy the whole leaf. The regulation 

 of atmospheric moisture, as I have 

 stated above, is one of the best prevent- 

 ive measures, and a dusting with lime 

 and sulphur mixed in about equal pro- 

 portions and applied when the foliage is 

 dry is good for preventing the spread 

 of the disease. We have tried Bordeaux 

 mixture with fair success, but it leaves 

 the plants unsightly and we have not 

 found it any more efficacious in prevent- 

 ing the spread of the disease than the 

 lime and sulphur.
